ACT ZM14-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit with Flywheel for 2019-2025 Mazda MX-5 Miata

Fits 2019-2025 Mazda MX-5 Miata (Sport, Club, Grand Touring, RF, and Special Editions).

The ACT ZM14-HDG6 Heavy Duty Race clutch kit is engineered for high-performance applications where rapid shifting and increased torque capacity are required. This kit combines ACT’s Heavy Duty pressure plate with a 6-pad, spring-centered race disc and a matched flywheel to deliver a complete driveline upgrade that handles significantly more stress than the factory components.

The Heavy Duty pressure plate utilizes an exclusive diaphragm design that undergoes a rigorous four-stage heat-treating process to maximize clamping load and service life while reducing deflection. Precision-stamped covers provide the rigidity needed for consistent pedal feel and repeatable engagement. The included 6-pad race disc features a spring-centered hub to damp torsional vibrations, protecting your transmission under harsh conditions. While the ceramic friction material provides harsher engagement than a standard street disc, it offers superior heat capacity and resists fade during repeated high-stress racing cycles.
