BMW Drivetrain Parts for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Looking to upgrade your stock clutch to something a little more beefy?  The performance clutch kits from DKM are a great option to help get power to the wheels without breaking the bank. Working with Competition Clutch, DKM clutch discs and plates are constructed using quality materials to obtain greater strength and heat tolerance than OE clutches, helping to prevent wear and tear while still giving you increased toque capacity for quicker shifts and more power management.

Stage 2 clutch kits are best for vehicles that may require an up-to 80% increase in torque capacity for heavily modified vehicles that will see a significant amount of track time. The clutch disc is improved, composed of a woven brass and organic material with alloy backings for better engagements at higher loads and extended clutch life.

This Stage 2 performance clutch kit includes the following items:

  • Pressure Plate
  • Sprung Organic Disc
  • Steel Single Mass Flywheel
  • Pilot Bearing/Bushing and Throw-out Bearing (when applicable)
  • Alignment Tool

Fits the Following Vehicles:

    BM9-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use 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 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 item fits the following BMWs:

    These aluminum mounts are a direct replacement for the stock rubber bushings and have been lightened to remove excess weight. Using aluminum instead of rubber eliminates the "wind up" inherent in rubber mounts, and this deflection slows suspension & drivetrain response. The tradeoff is an increase in NVH. Features: Stiffens chassis/Improves stability Less wear of other components Better durability Provides better control of chassis geometry Replaces OE: 33172282484 Recommended for racing use only Includes: 2 rear aluminum bushing 1 front aluminum bushings
