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 4-pad spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even 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 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.\nHD\/Race Sprung 4 Pad\nLight 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\n\u003cul\u003e\n  \u003cli\u003e\"Excellence in Performance\", backed by the best one-year warranty in the industry!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe ACT ZM2-HDG4 HD\/Race Sprung 4-Pad Clutch Kit is engineered for high-horsepower street and race applications requiring strong clamping force, rapid shifting, and dependable operation under demanding conditions.

Each diaphragm undergoes a four-stage heat-treating process, while precision cover stampings improve rigidity and consistency. The spring-centered race disc uses ceramic friction material for high heat tolerance and performance, with reinforced spring retainers that help reduce stress concentrations and resist failure during severe use. Engagement is more aggressive than an OE-style clutch, supporting faster shifting with light to moderate pedal effort and mild gear rattle.\u003c\/p\u003e\u003cp\u003eEvery ACT ZM2-HDG4 assembly is carefully engineered, precisely assembled, accurately balanced, 100% clamp-load tested, and dynamically computer balanced for smooth, reliable operation at high engine speeds. The 4-pad design is particularly well-suited to smaller disc applications and smaller engines. This clutch kit is designed for moderate friction life, with longevity supported by ACT’s diaphragm technology. It is backed by ACT’s one-year warranty and is listed for select Mazda Miata applications, including 1994 through 1997 and 1999 model years.
