The Action Clutch Stage 3 (1MS) kit with lightened flywheel for the 2003 BMW Z4 2.5L DOHC RWD uses a heavy-duty diaphragm pressure plate, reinforced drive straps and a sprung MIBA ceramic disc (4- or 6-puck) to deliver quick engagement and increased durability.

Expect quicker engagement and some clutch chatter during break-in.
