BMW E46 M3 Performance Clutch Kits & Parts

The STR Clutch line-up was designed to hold high capacity power while still retaining a relatively light clutch pedal. This technology was driven from our racer's demand for a lighter clutch during long endurance races in Japan. Heavy clutch pedals lead to driver fatigue during long endurance racing. Available in single and twin plate configurations matched with a unique clutch cover which allows for factory like clutch pedal feel.

Whether your E46 M3 is used for drag racing, drifting, or just embarrassing exotic supercars on the street, you need a clutch that can handle the abuse. This Twin Disk / Flywheel kit is ideal for cars with up to 1000hp including Turbocharged or Supercharged E46 M3's. 

Everybody is on a budget these days and the coin spent on some of the best parts does not have to spin up as fast as your boost gauge. 

Developing class-leading flywheel and clutch technology to even greater heights, UUC has developed a significantly new Twin Disk flywheel/clutch package designed for BMWs developing the highest levels of power from a turbo boost or supercharging. Two disks is that much more torque capacity and that much more tolerance of hardcore flogging.Amazingly, they have done this at a price competitive with the best traditional single disk systems. 

Until now, taming a 600hp+ BMW meant living with a clutch that was the stereotype "on/off switch" with rough engagement characteristics that made daily-driving a compromise. By incorporating larger disks than the average multi-disk clutch, the UUC design maintains original equipment smooth operation yet easily handles power levels approaching 1,000hp. 

Larger surface area of a smoother-functioning material is the key to combining the characteristics of high torque capacity with street-friendly operation in this all-new design. This may be the rare combination in high performance of best bargain and best performance. 

Total rotating mass of the complete flywheel and twin clutch package is 25.5lbs, the same total mass as a typical 11.5lb flywheel coupled with the M3 clutch. 

Choose the Organic compound for cars with less than 850hp or the Feramic compound for cars with less than 1000hp.

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate  pedal feel, and heat treated diaphragms for increased strength and performance.

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.

The ultimate in a racing flywheel and clutch! This was developed for use in our E36 and E46 World Challenge Touring Cars. The combined weight of the clutch and flywheel is only 11lbs!!!

This multi-disc (2 or 3 disc setups) offer a minimal flywheel mass (enough to include a factory ring gear for the starter) and a small 5.5" clutch assembly rated to 500ft-lbs. By saving as much weight as possible less energy is used in simply spinning the flywheel/clutch assembly and that means a lot more power and torque is available at the drive wheels. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines and this is among the most advanced and lightest racing clutch kits available for your BMW race car.

The JB Ultra-Light Performance racing clutch is available in 2-disc or 3-disc setups. A 3-disc setup is less susceptible to heat and will have a higher torque capacity. On our M54-powered 325i Touring Cars (approximately 300hp) we used the 5.5"/140mm 2-disc configuration. The 5.5" clutch was a perfect blend of performance and durability. It wasn't too small to suffer from high temperatures and wasn't too large that it couldn't be slipped (slipping prevents damage to other components). This is a turn-key racing clutch and flywheel kit that you don't have to engineer or spec yourself. This is the same clutch setup we used when winning the 2003 and 2004 Touring Car Championships - the quality and performance is unquestionable. That series also employed standing starts at each race and this clutch setup performed flawlessly with nearly a full season of racing on them before needing a change.

JB Ultra-Light flywheels include:

precision CNC machined aluminum flywheel

zero-balanced

replaceable hardened steel clutch friction surface

Helicoil threaded inserts

high-strength grade 10.9 hardware

multi-disc Sachs or Powertrain Technology racing clutch with racing pressure plate

JB Racing throw-out bearing with custom bobbin
This is a true racing clutch and will not function as a street-able clutch at all. It behaves as an on/off switch with no slippage allowed. Extreme care must be used when driving on to trailers and around the paddock. But when driven correctly the life span of this clutch is amazing - we could get a full season of racing a 300hp M54 from this clutch setup including standing starts at every race! Replacement clutch components and flywheel rebuilding are available.

A properly adjusted clutch stop is required for use with this clutch kit.

Stock Flywheel + Clutch Weight = 45+lbs
JB Ultra-Light Flywheel & Clutch Weight = 11lbs

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

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.

E46 M3 SPEC Clutch Kit contents:
+ carbon-Kevlar clutch disc
+ heavy-duty pressure plate

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features a Heavy Duty pressure plate, an G4 racing clutch disc, and an XACT Streetlite Flywheel.

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate  pedal feel, and heat treated diaphragms for increased strength and performance.

Next in this kit is the G4 racing clutch disc. This disc is a sprung, 4-pad disc that is suited for high horsepower road and track style racing. The G4 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. Also featured are heavy duty torsional springs that are rated for the clutch kit's expected uses. Over stock, this clutch kit has a much higher torque capacity and is better for quick shifting thanks to lower weight and inertia. Despite its ceramic racing style pads, this disc has great durability. In turn, these pads provide higher heat tolerances and faster, more aggressive clutch engagements.

The final main component is the XACT Streetlite Flywheel. This option is the most popular thanks to it versatility for street driving and drag/track style racing, its lighter weight for increased throttle response, and its single mass design.

This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for the E46 M3. Instead of picking a clutch from another car that may or may not work at all, the engineers at JB Racing have taken all of the guess work out of this upgrade and incorporated a Sachs sport sprung-hub clutch with the correct pressure plate and combined it with their most-popular aluminum lightweight flywheel. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock M3. Mixing and matching of the incorrect clutch, pressure plate, and flywheel components can lead to inconsistent engagement and feel -- why make your clutch feel worse?

In addition, the Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit. And with the aluminum flywheel weight savings is substantial over the stock dual-mass flywheel - which allows your motor to spool up faster and transmit more HP to the ground.

Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price).

Sport Clutch and Flywheel Applications:
2001-2006  E46 M3  (manual transmission only)

Ensure your clutch system can get the all of the power to the wheels. Stock clutch components lack the ability to transmit the full torque and horsepower loads to the wheels without suffering from increased wear and eventual clutch fade. Sachs Performance Clutch Kits are designed for sport and race applications, delivering higher torque transmission without succumbing to wear and tear and fading over extended periods of abuse.

Sachs Performance Clutch Kits include the following upgraded components:

• Performance Pressure Plate - Increased clamping force and resistant to wear

• Performance Clutch Disc - Allows for higher clamping force, higher torque transmission, and better clutch engagement at higher RPM’s

• Performance Throwout Bearing - Designed for increased spring pressure and higher RPM function

These kits are available with two different clutch discs, Organic and Metallic. Organic clutch discs are perfect for both performance street and light-moderate track applications. Metallic are designed for specifically for full-time track use such as endurance racing, clubsport, autocross, hill climbing and 1/4 mile racing. Please be sure you are purchasing the kit that best fits your needs. Our sales staff can help with any questions or concerns you may have!
