Mazda MX-5 Miata Clutch Kit - ACT - HD/Race Sprung 4 Pad (2019–2025). Built for drivers who demand crisp shifting and dependable power transfer, this kit combines ACT’s Heavy Duty pressure plate with a spring-centered 4-pad race disc.

ACT’s exclusive diaphragm design increases clamp load, reduces deflection, and helps extend clutch life. The diaphragm is treated through a four-stage heat process, and precision cover stampings add rigidity and consistency. The spring-centered 4-pad race disc uses wraparound spring windows and thicker retainers to damp torsional vibration for quieter operation and resist failure under harsh use. Expect light to moderate pedal effort with aggressive engagement; gear rattle can range from OE-like to mild. Select ceramic friction materials provide high heat tolerance, and every unit is 100% clamp-load tested and dynamically balanced for reliable high-RPM use. Suitable for high-horsepower street or race applications.
