ACT Heavy Duty race sprung 6-pad clutch kit for 2007 BMW 135, 335, 535, 435 and Z4 models. It combines the heavy-duty diaphragm pressure plate with a 6-pad spring-centered race disc that damps torsional vibrations and resists failure under harsh conditions. The spring retainers and heat-treated chrome-moly hub increase strength; engagement is firm for faster shifts and higher heat capacity. One-year warranty.
