The ACT ZM5-HDSS clutch kit is designed for Mazda MX-5 Miata models from 2007 to 2014, delivering enhanced performance and durability for street and light race applications. Featuring ACT's most popular heavy-duty pressure plate, this kit utilizes an exclusive diaphragm design that increases clamp load, reduces flex, and extends clutch life. The precision-engineered cover stampings ensure consistent rigidity and smooth engagement, providing reliable performance even at higher RPMs. The kit includes high-quality organic performance street discs with high copper content for superior heat transfer and a steel-backed lining for increased burst strength and durability. These discs feature a reduced marcel to enable faster shift action and smoother operation, ideally suited for spirited street driving or light racing. The combination of a heavy-duty pressure plate and high-performance clutch discs results in a clutch system that offers light to moderate pedal effort, positive engagement, and longer friction life, all backed by ACT's industry-leading one-year warranty. The components are carefully assembled, balanced, and tested to ensure high reliability and consistent performance under demanding conditions.
