Action Clutch Stage 4 clutch kit for 1998–1999 BMW 323is (2.5L M52) uses a heavy-duty single-diaphragm pressure plate, reinforced drive straps, and an Unsprung MIBA Ceramic disc (4- or 6-puck) for rapid engagement and durability. The kit includes a lightened flywheel and offers roughly 170% increased holding capacity versus stock. Built for dedicated race use, expect sharper engagement and some chatter during break-in.
