Clutch Masters FX100 clutch kit for 2014–2018 BMW F80 M3 and F82 M4 with S55 6-speed is a street-oriented upgrade that increases holding capacity by about 70%. It pairs the Power Plus I heavy-duty pressure plate with a steel-backed organic friction disc for stronger clamp while keeping near-factory pedal feel and smooth engagement. This sprung-disc kit fits single-mass flywheels and will not work with dual-mass units.
