Description: The ZM4-HDR6 kit by ACT features their most popular Heavy Duty pressure plate matched with a 6-pad rigid race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, diminish deflection, and extend clutch life. Each diaphragm undergoes a four-stage heat-treating process for exceptional performance. Precision cover stampings ensure rigidity and consistency.

ACT's 6-pad rigid race discs are constructed with high-quality ceramic friction materials and a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design facilitates quicker shifts and smooth, trouble-free service. Although engagement with the 6-pad rigid race disc is harsher, shifting is faster, making it ideal for race applications and larger clutch sizes to absorb more heat.

Key Characteristics:

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

Recommended Use: Recommended for race use only, suited for applications 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, GS, and 25th Anniversary Edition. All models equipped with the 2.0 L4 GAS FI 2000cc engine.
