The Action Clutch Stage 3 (1MS) clutch kit for 1999–2002 BMW Z3 (2.5L/3.0L RWD) is a robust single-disc option with a lightened flywheel, featuring a heavy-duty diaphragm pressure plate, reinforced drive straps, and a sprung MIBA ceramic disc (4- or 6-puck). It offers quicker engagement and improved durability for low to mild horsepower setups, with some expected chatter during break-in and increased holding capacity for demanding street or occasional track use.
