The Clutch Masters FX725 twin-disc clutch kit is engineered for high-performance applications, especially suited for drag racing enthusiasts and demanding automotive projects requiring exceptional power handling. With a 7.25-inch (184mm) diameter, this twin disc system features advanced ceramic rigid discs designed for maximum torque capacity while minimizing rotational mass, ensuring rapid throttle response and superior clutch engagement. The FX725 clutch kit is optimized for smaller bell-housings, making it an ideal upgrade for BMW 135i and 335i models from 2007 to 2010, with specific fitment for vehicles equipped with the N54 engine. Although primarily designed for racing, recent improvements in friction material have made this clutch capable of handling occasional street driving, providing a reliable solution for high-performance street cars that also see track use. The kit includes a precision-engineered aluminum flywheel, which helps reduce rotational inertia, allowing for quicker engine response and better acceleration. It is important to note that this conversion kit is designed to work exclusively with Clutch Masters flywheels and will not fit with OEM flywheels, ensuring optimal performance and longevity of the clutch system. Proper installation requires attention to mechanical linkage, precise pushrod alignment, and verification of a straight, unbinding travel path to prevent premature wear or binding of internal components. Our shop experience specializing in heavy-duty brakes since 1985 informs us that correct clutch setup is crucial for maintaining fleet reliability and high-performance consistency.
