ACT BMW Drivetrain Parts

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 a Heavy Duty pressure plate and an R6 racing clutch disc.

**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**

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.

This clutch kit features a Heavy Duty pressure plate and a G6 racing clutch disc.

**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**

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.
