BMW Performance Clutch Kits & Parts

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

Give your factory clutch a heavier motorsport feel or make your extremely tough clutch more drivable! If you have an E36 there is absolutely no reason you don't have this clutch pedal! Your factory E36 clutch pedal is made of flimsy plastic with no adjustment at all, leaving you to the mercy of the clutch you have.

Our Turner Performance Adjustable Clutch Pedal is a rigid design that gives you the ability to fully adjust your clutch feel and performance. With both upper and lower adjustments this is the best pedal on the market to fine tune your clutch pedal just the way you like it. The upper eccentric provides an adjustable pedal ratio to fine tune clutch pedal effort(how heavy the pedal feels). The lower adjustment is to change the position of the clutch assist spring, this allows you to choose where the clutch assisting spring engages. Changing where the spring engages will move the area of tension on your clutch from lower, middle to higher for maximum adjustment.

Your race car no longer needs to have a clutch that makes the car undriveable on the street. Your track car can now be your daily driver or weekend cruiser.

Features:

Adjustable throw
Capable of quicker shifts
Three lower mounting points for the spring to adjust where the assistance engages
Eccentric mount for master cylinder to adjust leverage ratio and pedal feel(weight/force needed to engage the clutch)
Self lubricating bronze bushings
All necessary hardware required for installation
Pedal body and pedal are constructed from 6061-T6 aluminum and type II black anodized for a great finish
NOTE: This Clutch Pedal does not include the Compression spring and the original spring must be reused. If you'd like to purchase a new spring, please see:

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

FEATURES & BENEFITS

Simplifies bleeding the BMW clutch hydraulic system by reducing trapped air in the slave cylinder Eliminates excessive pedal pumping and inconsistent clutch feel Helps achieve firm, consistent clutch pedal engagement Crafted from high-quality aluminum for strength and longevity Durable black anodized finish resists wear and corrosion Designed for both DIY enthusiasts and professional technicians PRODUCT DEVELOPMENT

Our Clutch Slave Cylinder Bleeder Tool was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Attention is always given to your shift linkage feel, whether it's replacing bushings, installing a short shift kit, or changing the height or weight of your shift knob. However, most enthusiasts don't think about the feel of their clutch pedal. Turner intends to change that with the introduction of the new Stainless Steel Clutch Lines, to provide a more direct and consistent pedal feel.

Under heavy and aggressive use, your stock rubber clutch line expands, resulting in a spongy pedal feel. This expansion is even more prominent in aged and weathered rubber lines. Turner Motorsport stainless reinforced clutch lines provide more confident and dependable shifting by maintaining consistent line pressure, long lasting corrosion resistance, and increased protection from failure. Our lines are reinforced with braided stainless steel mesh, affording superior expansion resistance over Factory and OE style clutch lines. This resistance to expansion creates a firmer pedal, and a more direct clutch pedal feel. The signature blue polymer coating provides additional protection from the elements and abrasion.

The best part about Turner clutch lines? They are manufactured in-house to the highest possible standard. All lines are made on dedicated, specialized equipment and each is tested to 3000 psi before being shipped.

Turner Motorsport stocks a large inventory of premium drivetrain components, including high-performance clutches, lightweight flywheels, short shift kits, upgraded bushings, and a wide range of shift knobs and pedal covers to suit your interior and your driving style. Everything you need to perform a professional quality transmission service, you can find here at Turner.

The factory BMW S55 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 26.5 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.

Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 18.5 lbs., this design significantly reduces rotational mass, allowing your S55 to achieve its true motorsport potential!

Features & Benefits:

Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
SFI 1.1 certified to ensure safe operation under extreme operating conditions.
Specifically designed to work with S55 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:

10 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 26.5 lbs.
Turner Motorsport Single-Mass: 18.5 lbs.
Faster revs
Improved throttle response and acceleration
Allows for a more engaging driving experience and delivers a feeling of direct connection
Installation:

Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

Engineered in-house, we designed this lightweight, single-mass flywheel to provide more than 10 pounds of weight savings over the factory flywheel. While some ultra-lightweight performance flywheels are manufactured from aluminum, our designers opted for a more driveable experience with steel. The mass provided by steel helps dampen vibrations and noise, delivering near-factory refinement with most of the benefits of a lightweight flywheel: quicker throttle response, improved durability (and longevity), and more effective transfer of power to the wheels.

Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

When it comes to selecting a clutch to pair with a lightweight flywheel, consider the driving you’ll be doing. As a single mass flywheel eliminates the dual-mass dampening of the factory flywheel, to retain the lowest noise, lowest harshness driving experience possible, select a clutch with a dampened disc such as the ACT Heavy Duty. For dedicated track cars, a solid clutch hub is appropriate.

Our recommendations:

Street: ACT Heavy Duty
Track: ACT Xtreme for high torque cars or OE 335is LuK (with 440lbs-ft or less)
Features:

Precision machined from 4140 HT heat treated chromoly steel for exceptional toughness, even wear properties, and durability.
Material quality promotes even wear across the entire friction surface
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability and elevated temperatures
Hardness improves wear characteristics
Black oxide coated for corrosion resistance on non-friction surfaces.
8620 steel pilot bearing pin, case hardened and Precision ground for maximum wear resistance.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
SFI 1.1 tested and certified to ensure safe operation under extreme operating conditions
SFI 1.1 specifies minimum material properties and requires a 3rd party lab certification test, spinning the flywheel to 1.5x redline for 1 hour to ensure the flywheel will not burst.
Specifically designed to work with N54 architecture clutches
Step height designed to optimize clamp load and maximize the usable range of clutch wear for a long service life
Performance:

Turner Flywheel 18.6 lbs
10 lbs lighter than the factory BMW flywheel (Stock Flywheel 28.9 lbs)
Faster revs
Improved throttle response
Improved acceleration
Sportier driving experience
Stock flywheel weight - 28.9lbs
Turner single mass flywheel weight = 18.55lbs

Single Mass Flywheel Conversion:

Audible chatter from the transmission after installation is considered normal. As with most single mass flywheels, there is less dampening in the flywheel to reduce "gear noise." This chatter noise may be more present when the transmission fluid temperatures are hotter and may be intensified by other modifications. Most gearboxes will experience some chatter noise at hotter temperatures. Please be advised that this noise will disappear once the clutch pedal is depressed. This symptom may be lessened by adjusting transmission fluid weight, turning off electrical/driveline consumers (A/C, High Beams, ETC.), and by raising the RPM slightly.

Installation:

Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

This kit uses the stock E36 M3 clutch with a JB Racing aluminum flywheel for an outstanding improvement in the non-M E36 328i/is. The stock M3 clutch is larger than the E36 328i disc and was used in the 321hp Euro M3 � way more clutch than you need on a 2.8-liter M52 (even supercharged cars). But because it�s a factory clutch the feel, durability, engagement, fitment, etc are OE spec! This package is in one of our own E36 328�s and has performed perfectly in over 60,000 miles of use.

  • OEM replacement clutch parts
  • lightweight aluminum flywheel for faster acceleration and quicker revs (15lbs less than stock)
  • comparable cost to OEM replacement parts
  • direct fit with no installation issues

    If you own an E36 but have never done a clutch job, you�re in for an unpleasant surprise! The stock flywheels don�t usually last much longer than 100,000 miles. You might be able to have it machined but only if you�re lucky. The best route is to have a new flywheel on hand when installing the clutch. This package is actually about the same price as buying a new OEM clutch and new OEM flywheel! And there�s a big performance boost!
      Included with this Clutch / Flywheel package:
    • E36 M3 3.2 Sachs OEM clutch kit - clutch disc, pressure plate, throw-out bearing
    • E36 M3 JB Racing aluminum flywheel
    • new pilot bearing
    • UUC Clutch Stop
    What about noise? This package was installed in Drew�s 1994 325is 60,000 miles ago. �I expected a trade-off when putting the aluminum flywheel on but the rattle is way less than what I was scared into believing. The rattle is not there all the time. And when I do hear it, I know what it is and immediately dismiss it. I�ve never had a bystander tell me to get my car checked out. And I�ve never had a passenger comment on it � they just ask why I�m revving the car so high� Without a doubt this will be a repeat mod on a future car. I�m using the regular Red Line MTL oil too.�

    This Clutch & Flywheel Package Fits:
    E36 328i, 328is, 328iC - 1996,1997,1998
    E36 M3 - 1995, 1996, 1997, 1998, 1999. Makes a great overhaul package!

    ARP Flywheel Bolts are a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated, ensuring complete heat penetration, to increase the clamping load up to 200,000 psi. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best bolts we've found and we highly recommend them in any and all applications. 

    ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

    As Used on Project E36 M3
    Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

    Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

    In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

    The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

    Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

    Improved acceleration (We measured a .4s decrease in 0-60 times on an otherwise-stock E36 328i!)
    Lower replacement cost
    Hardened 4140 Chromoly Steel for excellent engagement feel and wear resistance; zinc plated for corrosion resistance
    Designed for use with any E34 M5 pressure plate and clutch for OE-type clutch feel
    Sprung-hub clutch disc to eliminate chatter at idle and reduce driveline shock loading
    Weighs in at just 16.5lbs!
    SFI tested and certified to ensure safe operation under all conditions
    Includes ECS performance flywheel, clutch kit with throwout bearing, pilot bearing and all flywheel and pressure plate hardware
    Why is SFI testing and certification important?

    The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure quality of both design and materials for flywheels utilized in competitive motorsports.

    Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.

    Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

    Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines.

    Lightweight flywheel and upgraded clutch kit for improved throttle response, acceleration, and clutch feel - the perfect setup for daily-driven vehicles with up to 400 Ft/lbs of torque.

    This performance clutch and flywheel kit utilizes an upgraded ECS E34 M5 clutch kit with their in-house engineered flywheel to fit all M5x and S5x motors with a 5-speed transmission. By eliminating the dual-mass flywheel and replacing it with a single-mass you are able to eliminate the slack and extra weight of the flywheel for a quicker throttle response and acceleration. Their upgraded clutch kit utilizes all the best features of the original M5 clutch with an upgraded pressure plate and clutch disc, with the new clutch you have a better, more engaged clutch pedal feel, engagement, and longevity.

    Whether you're replacing a worn-out clutch or upgrading for increased power handling, this E34 M5 clutch and flywheel kit offers a reliable solution for enhanced pedal feel, power capacity, and overall driving satisfaction.

    Paired with a modified geometry flywheel, the E34 M5 style clutch is ideally suited for most E36, E46, and others using the same powertrain. It checks all the boxes for essential clutch replacement features. While some aftermarket options may address slipping issues and worn-out clutches, they often sacrifice pedal feel, providing little to no resistance. A soft clutch not only kills the driving experience of your BMW but also reduces confidence when pushing the car to its limits.

    On the contrary, you might be in the market for an upgraded clutch to handle your modified engine/forced induction builds. You go from an OE or aftermarket clutch option that has a lackluster and soft pedal feel to the complete opposite side of the spectrum, a very stiff clutch that grabs like an on-and-off switch making the clutch a pain almost undrivable on the street resulting in your favorite car turning into your least favorite car to drive.

    The E34 M5 clutch and flywheel kit balances performance with practicality, ensuring a satisfying driving experience whether you're maintaining your BMW or preparing it for increased power demands.

    Lightweight flywheels have proven themselves to be a worthwhile performance enhancement. But with the quicker throttle response and horsepower improvement comes one serious drawback: flywheel chatter. Without the dual-mass flywheel's rubber isolators, a lightweight aluminum flywheel has more rattle than stock. ECS has designed this flywheel using chrom-moly steel and it weighs almost ten pounds less than the stock DMF but not as extreme as full aluminum flywheels. The steel helps dampen vibration and noise so you get near-factory refinement and most of the benefits of a lightweight flywheel: quicker throttle response, better reliability, and more power to the wheels. Zero-balanced and SFI 1.1 certified (material and design has been independently burst tested to ensure quality and safety). This flywheel requires the E34 M5 sprung hub clutch kit. Choose below from the flywheel only or a complete kit.

    Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

    Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

    Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

    In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

    The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

    Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

    Enhance Your Car's Performance with the Perfect Clutch-Flywheel Combination

    When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.

The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

    The Stage 3+ is for cars making serious levels of boost and torque. If you have upgraded turbos or a single-turbo conversion, or have checked off the list of full bolt-ons, this will be a very capable clutch for you. This clutch is designed to work only with a SPEC single-mass flywheel and avoid the pitfalls of the stock OEM flywheel. The stock dual mass flywheel uses springs and rubber to isolate vibrations from the engine and transmission. However, on high mileage or abused flywheels the rubber can break down and the springs will become weak. A worn dual mass flywheel limits the amount of torque you can put out. It will affect clutch engagement, shifts, and power delivery. In some cases a total flywheel failure can rip apart the flywheel, clutch, and even transmission housing. With the SPEC single-mass flywheel the limitations of the stock flywheel are eliminated. The SPEC flywheel is a single mass design (no internal springs or rubber to fail) and is offered in a steel or aluminum material. The steel will better dampen vibration than the aluminum so it's the better choice for street use. The aluminum will have greater vibration and noise (gearbox rattle) that may not be acceptable for everyone. The clutch in this Stage 3+ kit is a sprung hub design so SPEC has done all they can to minimize the noise and vibration. It's also self-adjusting, like the factory design, and the engagement point can be adjusted. For use with SPEC Billet Flywheel (E-Chassis cars) or (F-Chassis cars)

    The SPEC Stage 2 clutch is a premium, no compromises heavy-duty clutch upgrade for the 2001-2006 E46 M3 (manual transmission). Where the stock clutch is well-known for premature wear when driven hard and the factory dual mass flywheel is a known failure point, the SPEC clutch delivers with an over-engineered, performance-oriented clutch solution. The single carbon-Kevlar clutch is rated at 545 ft-lbs, more than enough for the naturally-aspirated S54 engines. A heavy-duty pressure plate and throw-out bearing complete the package.

    The stock clutch in the S54 cars is not a terrible clutch and it is not under-rated (it's the same clutch disc used in the E39 M5). Our tuned M3 street and race cars have used the stock clutch with almost 400hp with only the occassional slip. But if the clutch is not grabbing like you want it to, or your tuning plans will include forced induction, a heavy-duty clutch is what will be needed. The SPEC Stage 2 clutch consists of a carbon-Kevlar friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The SPEC clutch is designed to work with the stock dual mass flywheel or the SPEC single-mass flywheel (steel or aluminum).

    The real weak point in the driveline is in the flywheel. The stock dual-mass flywheel has rubber damper discs inside that will wear out over time. Heat and aggressive driving will accelerate their wear. Even if the clutch contact surface is not showing wear the inner rubber linings most likely are. On most clutch replacements we strongly advise getting a new flywheel at the same time to avoid duplicating the work. You can use the SPEC clutch with the stock or SPEC flywheel. Both the SPEC steel and aluminum flywheels are lighter than stock and will be single-mass. There will be a lot more noise and 'gearbox chatter' with the aluminum but the tradeoff is a much better acceleration and quicker revving. For daily driver commuting you will probably be happiest with the stock flywheel. For the ultimate in sports car feel use the aluminum. For the best of both worlds select the SPEC steel flywheel. It will not fail like the dual mass design but still has enough mass to dampen most engine vibrations.

    SPEC Clutch is one of the premier clutch and flywheel suppliers to the tuner market. They are often found on the most highly tuned import and domestic vehicles. They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output. SPEC has been proven time after time to provide superior performance, drivability, and longevity to the most hardcare enthusiasts around the globe.

    From the factory, the E46 M3 featured a dual-mass flywheel and self-adjusting clutch kit. While this provided an easy, comfortable driving experience, it lacks the durability and performance features of an upgraded clutch and flywheel kit. ECS Tuning's all-new S54 performance clutch kit is designed to address these issues. Featuring a full-face clutch disc and heavy-duty pressure plate, this kit offers increased power-holding capability, exceptional pedal feel, and superior durability.

    The factory dual-mass flywheel weighs 24.2 lbs. This heavyweight component favors dampened vibrations and smooth gear changes—not performance. The 16.5 lb. E34 M5 flywheel designed by ECS omits the bulky dual-mass design for a single-mass, chromoly steel flywheel. For the performance-minded enthusiast, this translates to quicker RPM changes, easier "heel-toe" downshifts, and improved acceleration.

    Engineered in-house with the enthusiast in mind, this is the perfect option for those wanting a lightweight flywheel and performance clutch, without the heavy pedal feel commonly associated with aggressive clutch kits. The ECS S54 performance clutch and lightweight flywheel are designed to accommodate all conditions: from Sunday drives through the country to the abuse of the track. No matter your driving style or ability, this is the flywheel and clutch kit for you.

    PART DESIGN

    ECS S54 Performance Clutch Kit:

    Compatible with any performance flywheel that is designed to accept an E34 M5 architecture clutch Sprung-hub clutch disc Includes ECS performance pressure plate, performance clutch disc, throwout bearing, pilot bearing, alignment tool, and all flywheel and pressure plate hardware ECS Single-Mass Lightweight Flywheel:

    Eliminates the factory dual-mass flywheel for: Improved throttle response Improved acceleration Lower replacement cost Hardened 4140 Chromoly Steel for excellent engagement feel and wear resistance Zinc-plated for added corrosion resistance Weighs in at just 16.5 lbs! SFI tested and certified to ensure safe operation under all conditions Why is SFI testing and certification important?

    The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure the quality of both design and materials for flywheels utilized in competitive motorsports.

    Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.

    PRODUCT DEVELOPMENT

    This Performance Clutch Kit & Lightweight Flywheel was designed, engineered, tested, and quality inspected by the ECS Research and Development team. ECS Tuning strives for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing an in-house 3D printer, and rigorous long-term product testing.

    Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

    Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

    In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

    The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can be rebuilt too with a new clutch contact surface.

    Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch).

    Stock Flywheel Weight = 16.5lbs
