Description: The ZM5-HDR4 kit by ACT features their most popular Heavy Duty pressure plate matched with a 4-pad rigid race disc. Utilizing an exclusive diaphragm design, ACT Heavy Duty pressure plates increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for optimal performance. Precision cover stampings ensure rigidity and consistency.

ACT's 4-pad rigid race discs are crafted with high-quality ceramic friction materials and a heat-treated chrome-moly hub for durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. While engagement with the 4-pad rigid race disc is harsher, shifting is faster. This disc is particularly suitable for smaller disc sizes in smaller engines.

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, uses select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for race use only, ideal for applications where durability, aggressive engagement, and high performance 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, equipped with the 2.0 L4 GAS FI 2000cc engine.
