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.

Designed with 100% comfort and low manufacturing costs in mind, BMW's factory carrier bushing offers a freedom of movement on all axis, resulting in "factory installed slop".

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

Made in the USA If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. We originally developed these mounts for E36 and E46 World Challenge racing but they also work perfect in BMW Modified and SCCA club racing and SpecE46 (SE46). These are machined from solid aluminum and have zero deflection. The engine torque will cause a rubber or urethane mount to flex or deflect. The stiffer the material the less movement there is and the more torque is passed through the driveline (instead of being wasted winding up the mount). At the transmission end the flex-free solid mounts will give smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We have designed these mounts so the engine is 5mm lower and the transmission is 1mm lower than the factory mounts. This helps lower the center of gravity for better balance and handling. We very strongly recommend using the transmission and engine mounts together as a complete kit. Mixing a rubber mount with a metal mount will cause undue stress on the mouting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used. This kit fits the E36, E46, Z3, and Z4 6 cylinder models listed below, including M3 models.

These are a no-compromise design for all-out racing use. Full solid aluminum mounts should not be used on street-driven cars. Because there is no material to absorb vibration these will be quite harsh for regular street use (track cars don't care about noise).

Subframe reinforcement kits are very strongly recommended to go along with these solid motor mounts to reduce the risk of damage to the subframe. The motor mount section of the subframe should be reinforced to prevent stress and failure of the subframe.

This item fits the following BMWs:
1992-1999 E36 BMW 323is 323ic 325i 325is 325ic 328i 328is 328ic M3

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
