Description: The ZX4-HDR4 kit by ACT features their renowned Heavy Duty pressure plate coupled with a 4-pad rigid race disc. Utilizing an exclusive diaphragm design, ACT's Heavy Duty pressure plates enhance clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a rigorous four-stage, heat-treating process to ensure unparalleled performance. Precision cover stampings contribute to the rigidity and consistency of ACT pressure plates.

The 4-pad rigid race discs are crafted with high-quality ceramic friction materials and feature a chrome-moly hub heat-treated for strength and durability. The lightweight, rigid design enables quicker shifts and ensures smooth, trouble-free service. While engagement with the 4-pad rigid race disc is harsher, shifting is faster. This disc is particularly well-suited 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, utilizing select ceramic friction materials for high heat tolerance and maximum performance.

Recommended Use: Recommended for race use only, ideal for drivers seeking high-performance clutch systems optimized for competitive racing environments.

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

Vehicle Fitment: Compatible with various Mazda models, including the 2006-2013 Mazda 3 Mazdaspeed and the 2006-2007 Mazda 6 Mazdaspeed equipped with the 2.3 L4 GAS FI 2260cc | DOHC engine.
