The Clutch Masters FX400 8-puck ceramic clutch kit for 2013–2017 Cadillac ATS 2.0L is an extreme-duty conversion tuned for street-driven vehicles. The FX400 family claims about a 170% increase in holding capacity; the 8-puck full-face design offers quicker, smoother engagement with reduced chatter thanks to a marcel cushion and a sprung hub. This kit is a conversion and requires a Clutch Masters flywheel rather than the OEM unit.
