BMW Drivetrain Parts for BMW Z4 M Roadster S54 (2003-2008)

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.

This Meyle replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life.

This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used.

Applications:
1995-1999 E36 M3 manual & auto transmission
2001-2006 E46 M3, M3 CSL manual and SMG transmission
1991-1995 E34 M5 3.6 and 3.8 manual transmission
1998-2002 Z3 M Roadster, M Coupe - S52 and S54 engine manual & Auto transmission
2006-current E85 Z4 M Roadster, E86 M Coupe manual transmission
