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!

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.

This item fits the following BMW Engines:

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.**

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 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.

South Bend Clutch Stage 3 Daily Driver clutch kits are recommended for a single mass flywheel (SMF), when the original design is a dual mass flywheel (DMF). These clutch packages are designed for high-horsepower vehicles desiring a start performance similar to OE. The pressure plate is race-engineered (SS) and SFI-approved with a significant load increase over stage 1 and 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20 to 25 percent. Discs are assembled with heat-treated wear-resistant hubs, as well as drive plates and springs for high-load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, creating a dual dampening effect that simulates OE start performance. A performance organic friction material with a high metal content increases torque and rpm capability—and maintains low operating temperatures, which reduce wear and glazing. South Bend Clutch Stage 3 Daily Driver clutch kits are the perfect match for your high-performance street machine and occasional track use.

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.

This item fits the following BMW Engines:
