The Clutch Masters FX250 dual-friction dampened disc clutch kit for 2014–2018 BMW F80 M3 / F82 M4 (S55, 6-speed) combines a heavy-duty Power Plus I pressure plate with Fiber Tough material on the pressure-plate side and steel-backed organic material on the flywheel side. It increases holding capacity for spirited street use and is a sprung-disc kit intended for single-mass flywheels; it will not work with dual-mass flywheels.
