The Clutch Masters FX850 twin-disc clutch kit with aluminum flywheel is a conversion package for 2009–2010 BMW 135i applications. Supplied as a dedicated Clutch Masters solution, the kit pairs twin-disc clutch hardware with an aluminum flywheel for higher-capacity clutching in modified drivetrains. This conversion will not work with the OEM flywheel and is engineered to function exclusively with the Clutch Masters flywheel supplied in the kit, so installation requires the matching Clutch Masters flywheel rather than the factory unit.
