Clutch Masters Factory Fit FX350 twin disc kit is developed for 2021+ BMW G80 M3 and G82 M4 with the S58 3.0L and a 6-speed manual transmission. The FX series expands disc surface area and reduces assembly weight compared with the factory twin disc to offer stronger holding capacity without abandoning street drivability. This conversion requires a Clutch Masters flywheel and will not work with the OEM flywheel.
