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 item fits the following BMWs with 8 bolt flywheel and build date up to 01/2009 or earlier:

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!

    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.

    Tuning your N54/N55 with all of the bolt-on upgrades? Don't allow your clutch or flywheel let you down! The stock clutch is fine for a stock car or just a simple software upgrade. But anything more and it quickly becomes the weak link (especially with drag races or hard launches). The 135i/335i/535i/Z4 35i SPEC Stage 2+ clutch kit is perfect for owners who want a performance clutch that works great with simple bolt-on modifications and will have a minimum of downsides or trade-offs. SPEC has spent considerable time and effort on the 335i models to produce a performance clutch and flywheel package that holds up to track and drag strip demands but is also easy to live with for daily driving. This clutch kit is meant to be used only with a SPEC flywheel.

    What was most important to them was offering a kit that has stock-like clutch pedal effort but will grab and hold when the car has been mildly tuned. Full bolt-on upgrades like software, intake, FMIC, E85 mix, or methanol demand a better clutch. The Stage 2+ with the flywheel has a peak torque rating of 545ft-lbs. With the SPEC single-mass flywheel the limitations of the stock flywheel are eliminated. The clutch in this Stage 2+ kit is self-adjusting, like the factory design, and the engagement point can be adjusted. The clutch disc has a sprung hub so it can be used with the single-mass flywheels with near-stock levels of noise, vibration, and refinement. See comments below for characteristics of each.

    The Stage 2+ can be configured a few different ways depending on how you intend to use the car -

    #SB533H-2 VariantUseComments
    "Sport"
    SPEC steel flywheel
    daily driving;
    occassional drag strip
    Use this with the SPEC steel single-mass flywheel.
    The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a steel single-mass is used instead. Expect more noise and vibration from the steel but better reliability and slightly better performance.
    "Super Sport"
    SPEC aluminum flywheel
    more drag strip than streetUse this with the SPEC aluminum single-mass flywheel.
    The clutch will be stiffer than the factory design but it will grab harder and stay connected with far less chance of slippage. The engagement point is changed but most drivers adjust within the first 100 miles. The failure-prone dual-mass flywheel is eliminated and a lightweight aluminum single-mass is used instead. Expect a lot more noise and vibration with aluminum ("gearbox rattle") but better reliability and better performance. The engine will rev a lot faster too.

    This clutch is what we recommend if your tuning plans will only be bolt-on upgrades and you want to eliminate the dual-mass flywheel (as a potential failure point). If you plan to go beyond bolt-ons, such as upgrading turbos or single turbo, we strongly recommended using the Stage 3+ clutch. The Stage 2+ offers the best drivability for 90% of the tuned 335s out there but when going beyond bolt-on upgrades it would be best to go to a more advanced clutch stage.

    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 hardcore enthusiasts around the globe.

    Next in this kit is the R6 racing clutch disc. This disc is an unsprung, rigid disc with 6 pads that is best suited for drag and road racing and handles heat better thanks to its increased surface contact area versus the 4 pad version of this disc, the R4. The R6 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Over stock, this disc is much better for faster shifting and significantly higher torque loads. Unlike the stock disc, this racing disk has a slightly shortened life span due to its rigid design and pad composition. This in turn is offset thanks to its fast, aggressive engagement for track use.

    BM9-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.

    The SPEC Stage 1 clutch is a premium, no compromises SPORT clutch upgrade for the 2001-2003 E46 330i/ci (5-speed 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 430 ft-lbs, more than enough for a naturally-aspirated M54 engine. A heavy-duty pressure plate and throw-out bearing complete the package.

    The stock 330 clutch was not designed for performance. It works fine for a daily driver street car with no mods but performance and longevity quickly drop off when adding more power or using the car for aggressive street, autocross, or track use. A lot of our customers also hate the self-adjusting clutch (SAC) mechanism and the clutch delay valve that makes clutch engagement inconsistent and unnatural feeling. It's no wonder that for the Grand-Am Cup touring car races the rules specified an E36 M3 clutch! If you're unhappy with the stock clutch feel or your future plans include additional upgrades that boost torque, then a heavy-duty clutch is what will be needed. The SPEC Stage 1 clutch consists of a hybrid carbon-Kevlar and organic 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 with a lightweight aluminum single-mass flywheel.

    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 an aluminum flywheel. A machined steel flywheel is also an option as a middle ground. 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.

    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.

    The SPEC Stage 2 clutch is a premium, no compromises heavy-duty clutch upgrade for the 2001-2006 E46 M3 (SMG 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.

    Every design is thoroughly researched and tested prior to release to guarantee their products meet and exceed the customer's expectations. Careful attention is payed to factors such as engine torque, maximum RPM, drive type (FWD, RWD, AWD), and the type of driving being done, such as street, sport, track events, racing, etc. ACT's clutch kits are competitively priced, often with  specifications greater than competitor's and at a higher quality.

    This clutch kit features a Xtreme pressure plate, an G6 racing clutch disc, and an XACT Streetlite Flywheel.

    Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

    The G6 clutch disc is a sprung, 6-pad racing disc that is recommended for high horsepower street and race us and is better at handling high heat than the 4-pad disc. Its material composition is high quality, ceramic friction materials and a heavy duty torsional dampening springs that are rate for this clutch disc's size and expected uses. It has an increased torque capacity, and is better for faster shifting with its low weight and inertia. Being a racing disc, it has good durability and its ceramic composition allows for high heat tolerances. It also has a fast, aggressive engagement in comparison to standard street-use clutch discs.

    The XACT Streetlite Flywheel is their most popular flywheel as it is great for both street and drag racing. It allows your engine to rev quicker, giving you increased throttle response, and is considerably lighter than your stock flywheel thanks to its light single-mass design, all while still being very durable!

    Clutch Kit Specs:

    • Torque Rating: 465 ft/lbs
    • 52% torque capacity increase over stock!
    • Type of Disc: Street
    • 10-count spline
    • Spline Size: 1-3/8" inch
    • Flywheel Weight: 15.1 lbs
    • 1 year Warranty from retail purchase date!

    The SPEC Stage 2 clutch is a premium, no compromises heavy-duty clutch upgrade for the 2006+ N52 E9X 325/328/330i. Where the stock clutch will slip under hard conditions and the factory dual mass flywheel is a known failure point, the SPEC clutch delivers with an over-engineered, performance-oriented clutch solution.

    Tuning your N54/N55 with all of the bolt-on upgrades? Don't allow your clutch to let you down! The stock clutch is fine for a stock car or just a simple software upgrade. But anything more and it quickly becomes the weak link (especially with drag races or hard launches). The 135i/335i/535i/Z4 35i SPEC Stage 2+ clutch kit is perfect for owners who want a performance clutch that works great with simple bolt-on modifications and will have a minimum of downsides or trade-offs. SPEC has spent considerable time and effort on the 335i models to produce a performance clutch that holds up to track and drag strip demands but is also easy to live with for daily driving. This clutch kit is meant to be used only with the stock dual-mass flywheel and is the most user-friendly of the SPEC clutches we offer for the 135/335/535/Z4.

    What was most important to them was offering a kit that has stock-like clutch pedal effort but will grab and hold when the car has been mildly tuned. Full bolt-on upgrades like software, intake, FMIC, E85 mix, or methanol demand a better clutch. The Stage 2+ has a peak torque rating of 545ft-lbs but note that the stock dual-mass flywheel will be a limiting factor to how much torque you can use. There have been cases of high mileage or abused flywheels coming apart with high torque tuned engines. We recommend using a new factory flywheel or jumping to the SPEC single-mass flywheel. The clutch in this Stage 2+ kit is self-adjusting, like the factory design, and the engagement point can be adjusted. The clutch disc is a rigid hub (not spring loaded) so it's best used with the stock dual mass flywheel.

    This clutch is what we recommend if your tuning plans will only be bolt-on upgrades. If you plan to go beyond bolt-ons, such as upgrading turbos or single turbo, we strongly recommended using the Stage 3+ clutch. The Stage 2+ offers the best drivability for 90% of the tuned 335s out there but when going beyond bolt-on upgrades it would be best to go to a more advanced clutch stage.

They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output.

    + carbon/semi-metallic and Kevlar clutch disc
    + heavy-duty pressure plate
    + heavy duty throw-out bearing
    + pilot bearing
    + clutch fork

    Additional items we recommend:

    flywheel mounting bolts (if removing flywheel)

    The SPEC Stage 4 clutch is designed for race and track use where light weight and a grippy clutch material are paramount to quiet and smooth operation on the street. The Stage 4 is popular in the SpecE30 racing series and for other track cars. It uses a rigid center hub with 6 clutch pucks and no springs instead of a full clutch disc. This makes the whole assembly lighter and simpler (less likely for a failure). The friction material is rated at 425 ft-lbs, more than enough for a naturally-aspirated E30. A heavy-duty pressure plate and throw-out bearing complete the package. If clutch or flywheel woes are keeping you from getting the most from your E30 this is the clutch you should be using.

    The stock clutch in the M20 E30 is not terrible but can become quickly overheated and lead to glazing on the flywheel surface and inconsistent engagement. A more robust material is needed to handle the extreme temperatures found at the track. The SPEC Stage 4 clutch consists of a carbon/semi-metallic 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 clutch is rebuildable to help minimize consumable costs. The SPEC clutch is designed to work with the stock dual mass flywheel or the SPEC single-mass aluminum flywheel. If this is for racing, check your rules to confirm which flywheel can be used.
