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!

On vehicles that have hydraulic clutches, the slave cylinder transmits pedal movements to the clutch pack. The hydraulic aspect of this system makes clutch engagement much more comfortable. Like any hydraulic system though, the corrosive brake fluid can wear out seals and cause leaking and failure. If this is the case on your car, the best solution for repair is replacing the defective part.

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.

Looking to eliminate your dual-mass flywheel? Overwhelmed with all the options, but hearing complaints about so many of them with rattling or chatter from them? Problem solved. Introducing the all-new Lightweight Performance Flywheel from ECS Tuning. Engineered in-house with the enthusiast daily driver in mind, this is the perfect option for those wanting a lightweight flywheel without the annoying chatter heard from so many other options on the market. 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.

Key Features:

Eliminates factory dual-mass flywheel for:
Crisper shifts
Improved throttle response
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.

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.

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.

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. Features: The flywheel has a peak torque rating of 545ft-lbs Limitations of the stock flywheel are eliminated Self-adjusting, like the factory design, and the engagement point can be adjusted Sprung hub clutch to be used with the single-mass flywheel with near-stock levels of noise, vibration, and refinement **Due to the nature of lightened single mass flywheels added "NVH" or "chatter" will or may occur during operation. Accompanying modifications can also increase or decrease the amount of "NVH" or "chatter" in the drivetrain. Please contact our sales team with any questions.**

This is a performance replacement for BMW Part # 21207533868 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.

According to BMW the single mass flywheel was installed in all 325i up to 12/86 production date but we have seen some later cars with a single-mass flywheel. 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)

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.

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.

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.

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).

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 E46 M3 does not suffer from the cooling nightmares of the previous E36 models. The original water pump uses a composite impeller, not plastic or metal, so the BMW pump will typically last 85,000+ miles before the bearings show signs of wear (the composite impeller is not the reason for preventative maintenance - it's the bearings). We prefer the OE BMW pump to the aftermarket brands because it uses the composite impeller, it has a proven reliability record, and the pricing represents a solid value upgrade. The pump is located on the front of the engine with the fan attached to it. The complexity of the S54 engine means the water pump has multiple gaskets and seals that should also be replaced. And if the thermostat has not been changed then this is the best time for a new one as well.

Composite vs Metal
BMW designed this water pump to use a composite impeller. It is much stronger than the plastic pieces that were so problematic in the mid-90s. The aftermarket solution to the plastic issues was to use a metal impeller. This solved the impeller issues but created some others. The metal impeller is heavier than composite or plastic and that led to quicker bearing failure on the E36 pump (sometimes within a year). The possibility exists that the same premature bearing failure can happen on the E46 M3 metal impeller pumps as well. The heavier weight also has the drawback of using more horsepower since it requires more effort to move the heavier piece. The composite materials solve all of these issues - light weight, strong, long lasting, and relatively inexpensive. They also come with a two-year warranty (most aftermarket pumps are one year). Original BMW water pumps for the E36 (and most other modern BMWs) now use a composite impeller so any issues with factory pumps are long gone. Original BMW water pumps for the E46 M3 are known to last over 100,000 miles and the composite is still in excellent condition (failure is usually typical leaks from worn bearings). For preventative maintenance we recommend a replacement around 85,000 miles. Alternate part numbers: 11517838118, 11517838159.
