BMW Drivetrain Parts for BMW Z Series E85/6 (2003-2008)

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.

As Used on Project E36 M3
This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for the BMW E36, E46, Z3, and Z4 models. 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 HD sprung hub clutch with the correct pressure plate and combined it with our 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 clutch. 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!).
