Action Clutch 97-98 BMW Z3 2.8L (M52) Stage 4 Clutch Kit (1MD) w/Lightened Flywheel

This Stage 4 (1MD) Clutch Kit from Action Clutch is engineered for demanding race applications, including drag, road, and drift racing. It features a heavy-duty single diaphragm pressure plate, reinforced drive straps, and an unsprung MIBA Ceramic disc (available in 4 or 6 puck configurations). This design provides peak performance, extreme durability, and a 170% increased holding capacity over the factory kit. The unsprung MIBA Ceramic disc offers quicker engagement but may introduce some clutch chatter, which should minimize after a proper 500-mile street break-in period (keeping RPMs under 4500, no more than half-throttle, and no boost if applicable). The kit includes a lightened flywheel (model AC111FW), alignment tool (model AT83), pilot bearing (model PB-6002-2RS), and release bearing (model SN3759). Action Clutch emphasizes that each kit undergoes rigorous quality checks by experienced engineers. It is important to select the correct clutch kit for the vehicle's engine power output to prevent premature clutch failure and potential transmission damage. All products are 100% hand-assembled in the USA.
