Designed for serious performance use, the OT-215 8.5” Cerametallic Clutch and Flywheel Kit is ideal for E46 M3 owners who track their cars regularly but still drive them on the street. This twin-disc setup delivers the perfect balance between a heavy, OEM-style 10.5"/11" clutch and a lightweight 7.25" race clutch.
The 8.5” Cerametallic design offers about 50% more mass than a 7.25” twin-disc setup, improving heat capacity and reducing clutch temperatures during extended track use. It provides higher torque capacity, better pedal modulation, and more consistent engagement—making it ideal for Pro Touring, Time Attack, and Track Day M3s.
Each 8.5” Cerametallic Clutch-Flywheel Kit for E46 M3 includes:
- OT-215 8.5” Cerametallic clutch assembly
- Disc pack
- Throwout Bearing
- Billet chromoly steel flywheel
- Clutch bolt kit
- Flywheel bolt kit
