8.5” Cerametallic Clutch-Flywheel Kit | E46 NON-M

Designed for high-performance street and track use, the OT-215 8.5” Cerametallic Clutch and Flywheel Kit is the ideal upgrade for E46 non-M models equipped with the M52TU or M54 engine. This setup delivers a balanced solution between the heavy, OEM-style 10.5”/11” clutch systems and the ultra-light 7.25” race clutches.

With approximately 50% more mass than a 7.25” twin-disc setup, the OT-215 offers greater heat capacity, helping keep clutch temperatures stable during demanding track sessions. The result is improved torque capacity, better modulation, and smooth, predictable engagement—perfect for Pro Touring builds, Time Attack, and Track Day E46s that still see occasional street use.

Each kit includes:

• OT-215 8.5” Cerametallic clutch assembly
• 1 E46 Non-M spline disc pack
• Billet chromoly steel flywheel
• Clutch bolt kit
• Throwout bearing
• Flywheel bolt kit
