Description: The ZM4-HDG6 kit by ACT comprises their most popular Heavy Duty pressure plate matched with a 6-pad, spring-centered race disc. ACT Heavy Duty pressure plates employ an exclusive diaphragm design to augment clamp load, diminish deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

The 6-pad, spring-centered race disc features a spring-center to appropriately 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. Engagement with the 6-pad, spring-centered race disc is harsher, but shifting is faster, making it recommended for larger clutch sizes to absorb more heat.

Key Characteristics:

• Feel: Light to moderate pedal effort, aggressive engagement, OE to mild gear rattle.
• Life: Moderate friction life, extended by ACT's exclusive diaphragm design.
• Quality: Carefully engineered, precisely assembled, accurately balanced, using select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for high horsepower street or race use, where quick, aggressive shifts are necessary.

ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Vehicle Fitment: Compatible with various Mazda MX-5 Miata models from 2006 to 2015, including Grand Touring, Sport, Touring, GT, Special Edition, Club, and GS. All models equipped with the 2.0 L4 GAS FI 2000cc engine.
