The Action Clutch Stage 4 (1MD) clutch kit with lightened flywheel for the 2003 BMW Z4 2.5L DOHC RWD features an unsprung MIBA ceramic disc (4- or 6-puck), reinforced drive straps and a heavy-duty single diaphragm pressure plate for peak durability and fast, on/off engagement. It’s aimed at race applications including drag, road and drift use, delivering about a 170% increase in holding capacity over factory. Some clutch chatter is normal during break-in.
