ACT ZM8-HDG6 HD/Race Sprung 6-Pad Clutch Kit for 2004-2011 Mazda RX-8

Fits 2004-2011 Mazda RX-8 models, including Base, R3, Grand Touring, Sport, Touring, and Shinka editions.

The ACT ZM8-HDG6 HD/Race clutch kit is engineered for high-performance applications requiring increased torque capacity and faster shifting. At the core of this kit is the ACT Heavy Duty pressure plate, which uses an exclusive diaphragm design and a four-stage heat-treating process. This construction maximizes clamp load and reduces deflection, ensuring consistent performance and rigidity through precision cover stampings.

The included 6-pad ceramic race disc features a spring-centered hub to damp torsional vibrations and reduce stress on the drivetrain under harsh conditions. While engagement is more aggressive than a standard street clutch, the ceramic friction material provides the high heat capacity necessary for racing. For added reliability, the disc utilizes wraparound spring windows and thick retainer stampings to prevent spring failure.
