The Action Clutch Stage 4 single-disc clutch kit for 1991–1993 Nissan Skyline GTS (2.5L RB25DE non-turbo, RWD) targets drivers building dedicated race cars. It pairs an unsprung MIBA ceramic disc (4- or 6-puck) with reinforced drive straps and a heavy-duty diaphragm pressure plate for aggressive, on/off engagement and increased durability. Expect some chatter during break-in; each kit is inspected by engineers and fitted with fully enclosed spring retainers to reduce catastrophic failure risk.
