ACT ZM14-HDG6 HD/Race Sprung 6-Pad Clutch Kit with Flywheel for 2019-2020 Mazda MX-5 Miata

ZM14-HDG6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. HD/Race Sprung 6 Pad Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT ZM14-HDG6 clutch kit is engineered for high-performance street and race applications using a Heavy Duty pressure plate and a 6-pad, spring-centered race disc. Its exclusive diaphragm design increases clamp load, reduces deflection, and helps maximize clutch service life. Each diaphragm undergoes a four-stage heat-treating process, while precision cover stampings improve rigidity and consistency for dependable operation at elevated engine speeds.

The 6-pad, spring-centered disc uses carefully selected ceramic friction materials for high heat tolerance and aggressive power transfer. Its spring-centered design helps damp torsional vibrations and resist failure under harsh conditions. Spring retainers with wraparound windows and thicker stampings improve spring support, reduce stress concentrations, and increase strength and reliability. Engagement is harsher than an organic street disc, but the design supports faster shifting and is recommended for larger clutch applications that require greater heat absorption.

ACT ZM14-HDG6 provides light to moderate pedal effort with aggressive engagement, moderate friction life, and potential for mild gear rattle. Every assembly is carefully engineered, precisely assembled, accurately balanced, 100% clamp-load tested, and dynamically computer balanced to promote smooth, reliable performance at high RPM. The kit is designed for high-horsepower street or race use and includes ACT's industry-backed one-year warranty. This automotive clutch kit fits select 2019-2020 Mazda MX-5 Miata applications; verify the vehicle configuration before ordering.
