Action Clutch Stage 4 (1MD) Clutch Kit for 2003–2008 Mazda 6 2.3L is an unsprung MIBA ceramic solution with a heavy-duty single diaphragm pressure plate and reinforced drive straps for aggressive engagement and increased durability. Intended for race-oriented use where quick engagement and high holding capacity are required, each kit is inspected and includes safety features; some clutch chatter during break-in is normal for this configuration.
