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.

Whenever you replace your clutch, you want to be sure that every single part that can be serviced while disassembled is new and in great shape. This saves you time down the road if a small component not serviced in a clutch change fails. This is a perfect replacement for your clutch pilot bearing with the same outside and inside diameter. A great way to be sure that everything installed during your clutch change works in harmony.
