Clutch Masters Factory Fit FX250 twin disc kit is developed for 2021+ BMW G80 M3 and G82 M4 with the S58 3.0L and 6-speed manual transmission. The FX series uses higher-end friction materials and increased disc area to sit between comfort and track-oriented options; the assembly reduces overall weight and expands disc surface. This conversion is built to be used with a Clutch Masters flywheel, not the OEM flywheel.
