The Action Clutch Stage 4 (1MD) clutch kit for 1999–2000 BMW 528i (2.8L RWD) pairs a heavy-duty single diaphragm pressure plate with an unsprung MIBA ceramic disc (4- or 6-puck) and reinforced drive straps. Intended for dedicated race applications, it produces quicker engagement and some clutch chatter during break-in. The kit raises holding capacity significantly; selecting the correct kit for engine output is critical to avoid damage.
