ACT Heavy Duty HD/Race Sprung 6 Pad Clutch Kit for Mazda RX-8 (Part Number: ACT ZM8-HDG6)

Upgrade your Mazda RX-8 with the ACT Heavy Duty HD/Race Sprung 6 Pad Clutch Kit, designed for high-performance driving and demanding applications. This kit features ACT’s most popular heavy-duty pressure plate, utilizing an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch lifespan. Each component undergoes a rigorous four-stage heat-treating process, ensuring durability and consistent performance under high heat conditions. The precision cover stampings in the pressure plate enhance rigidity and provide consistent engagement, making this clutch suitable for both street and race use. The 6-pad, spring-centered race disc offers an aggressive engagement feel and faster shifting, ideal for high horsepower applications and track days. Its design includes a spring-center that effectively dampens torsional vibrations and withstands harsh conditions, reducing the risk of failure. ACT’s wraparound spring retainers with thicker stampings improve spring support, distribute stress more evenly, and boost overall reliability. Engineered for high heat tolerance with high-quality ceramic friction materials, this clutch kit ensures extended friction life and smooth operation at elevated temperatures. The assembly is carefully balanced and 100% clamp load tested, providing reliable, high-RPM performance with minimal chatter or gear rattle. Suitable for larger clutch sizes, this kit is recommended for enthusiasts seeking aggressive engagement and durability for street or race environments. Backed by ACT’s industry-leading one-year warranty, the ACT ZM8-HDG6 clutch kit is an excellent choice for high-performance Mazda RX-8 owners demanding quality, reliability, and maximum power transfer.
