The Clutch Masters Factory Fit FX400 Series Twin Discs clutch kit for the 2021+ BMW G80 M3 and G82 M4 equipped with the S58 engine provides a reliable upgrade for high-performance street and light track use. Designed to bridge the gap between OEM comfort and race-oriented durability, this kit ensures a smooth driving experience while offering increased torque capacity to handle tuned and modified vehicles. The kit is engineered specifically for the 6-speed manual transmission models, maintaining factory-like engagement and pedal feel without sacrificing reliability under demanding conditions.
This conversion kit is built exclusively to work with Clutch Masters flywheel, as it is incompatible with OEM flywheels. It features a high-performance, 8-puck twin disc design optimized for aggressive driving, yet retains street-friendly drivability. The FX400 series provides an excellent balance for enthusiasts seeking a durable clutch solution that withstands increased power output without the harsh engagement typical of full race setups. Its construction emphasizes high clamp load, heat dissipation, and longevity, making it ideal for both daily drivers and spirited driving on weekends.
Installation requires careful attention to the mechanical linkage and proper alignment of the pushrod to prevent premature wear or binding. Our shop experience specializing in heavy-duty brakes and drivetrains since 1985 has shown that ensuring a straight, unbinding travel path during clutch system assembly is critical for optimal performance and longevity. This kit supports fleet reliability and is suitable for owners who demand a high level of durability in their daily and performance vehicles.
