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

Clear BMW chassis

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.

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 an Xtreme pressure plate, a Performance Street sprung 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.

Next in this kit is the Performance Street clutch disc. This is the most popular sprung clutch disc and features high quality organic friction material with a high copper content for improved heat transfer and a steel backed lining for increased strength in burst load circumstances. This organic clutch disc has a significantly higher torque capacity than a stock disc but still retains a long life span and operates quietly and reliably.

Clutch Kit Specs:

Torque Rating: 520 ft/lbs
68% torque capacity increase over stock!
Type of Disc: Street
26-count spline
Spline Size: 1-3/8" inch
Disc Weight: 3.5 lbs
Pressure Plate Weight: 10.7 lbs
1 year Warranty from retail purchase date!
