The Clutch Masters FX400 6-puck ceramic clutch kit for 2013–2017 Cadillac ATS 2.0L is an extreme-duty conversion intended for race or aggressive street use. The FX400 system advertises roughly a 170% increase in holding capacity and pairs a heavy-duty pressure plate with a sprung ceramic disc to balance strong holding and moderate dampening. This conversion requires a Clutch Masters flywheel and will not work with the OEM flywheel.
