BMW Drivetrain Parts for BMW Z4 M Roadster S54 (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.

Located between the transmission and driveshaft, the giubo (also giubo) joint is a flexible rubber drive coupling that joins driveline components to reduce vibration, while allowing a limited range of flexibility. Joint rubber deteriorates over time from torque stress and heat hardening. A failed joint is a common cause of driveline noise and vibration. This kit includes a new drive shaft center mount with bearing to insure proper driveshaft placement. Includes Driveshaft center support bearing (csb) Driveshaft front flex disc (giubo) installation hardware for flex disc and center support bearing Driveshaft centering bearing Butyl tape for center support bearing insulation
