The ACT ZX4-HDG6 Heavy Duty Race Sprung 6 Pad Clutch Kit pairs ACT's most popular Heavy Duty pressure plate with a 6-pad spring-centered race disc for the turbocharged Mazdaspeed 3 and Mazdaspeed 6. The Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load and reduce deflection, with every diaphragm undergoing ACT's four-stage heat-treating process and precision cover stampings for rigidity and consistency. The 6-pad spring-centered race disc dampens torsional vibrations and resists failure under harsh conditions; wraparound spring windows and thicker retainer stampings on the spring retainers add support, reduce stress concentrations, and increase strength. Engagement is harsher and shifting is faster than a street disc, and the 6-pad configuration is recommended for larger clutch sizes that need to absorb more heat.
