ACT 19-25 Mazda MX-5 Miata HD/Race Sprung 6 Pad Clutch Kit w/ Flywheel | ZM14-HDG6

The ACT ZM14-HDG6 kit features ACT's most popular Heavy Duty pressure plate paired with a 6-pad, spring-centered race disc and flywheel for the 2019-2025 Mazda MX-5 Miata. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life, with every diaphragm heat-treated in a four-stage process. The 6-pad, spring-centered race disc uses a spring center to properly damp torsional vibrations and resist failure under harsh conditions, with wraparound spring windows and thicker retainer stampings for added strength. Engagement is harsher than a street disc, but shifting is faster, and the design is recommended for larger clutch sizes that need to absorb more heat.
