The Clutch Masters FX300 clutch kit for 2009–2013 BMW M3 (4.0L) is supplied as a sprung-disc upgrade engineered to meet OEM single-mass flywheel specifications. It provides a higher-capacity friction assembly intended for aggressive street use while maintaining functional engagement characteristics. Confirm compatibility with a single-mass flywheel, as this kit will not work with dual-mass flywheel assemblies.
