The ACT 2004-2011 Mazda RX-8 HD/Race Rigid 4 Pad Clutch Kit is engineered for high-performance driving and racing applications. Featuring ACT's most popular Heavy Duty pressure plate, this kit utilizes an exclusive diaphragm design that increases clamp load, reduces deflection, and extends clutch life. All diaphragms undergo a four-stage heat-treating process, ensuring durability and consistent performance under demanding conditions. Precision cover stampings provide added rigidity and uniformity, contributing to smoother engagement and reliable operation. The kit includes ACT's 4-pad rigid race discs made with high-quality ceramic friction materials, offering high heat tolerance and aggressive engagement for quick, decisive shifts. The chrome-moly hub is heat-treated to maximize strength and durability, making this clutch suitable for intense racing environments. Its lightweight, rigid design facilitates quicker shifts and trouble-free service, although engagement may be harsher, and pedal effort is light to moderate. Designed primarily for race use, this clutch kit may increase gear rattle and spline wear over time but delivers exceptional performance during high-RPM driving. Each component is carefully engineered, precisely assembled, and dynamically balanced for smooth operation at high speeds, backed by ACT's industry-leading one-year warranty. The kit is compatible with various Mazda RX-8 models from 2004 to 2011, providing a robust solution for enthusiasts seeking maximum performance and reliability in racing or spirited driving scenarios.
