OS Giken BMW Performance Clutch Kits & Parts

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

This racing flywheel and clutch kit is made by renowned drivetrain specialist OS Giken. Complete fly wheel & clutch setup as used on our own TMS E92 M3 race cars. This setup is ideal for both endurance racing or high horsepower applications that have very limited street use but require more clamping power than stock. It has been approved for use in the GRAND AM Continential Challenge GS race class, approved by GRAND AM rules and regulations.

Includes flywheel, clutch discs (2 disc clutch), center plate, pressure plate, aluminum cover, 360 degree housing (for clutch assembly), cover bolts, flywheel bolts, throw-out bearing, and release sleave assembly. Weighs 5% less than the stock E90/E92 M3 flywheel and clutch setup. This setup is intended for racing use only (not for daily driven street cars.) We recommend using the OS Giken clutch alignment tool during installation (sold separately).
