ACT ZM4-HDG6 Heavy Duty Race Sprung 6-Pad Clutch Kit for 2006-2015 Mazda MX-5 Miata

Fits 2006-2015 Mazda MX-5 Miata models.

The ACT ZM4-HDG6 Heavy Duty Race clutch kit is engineered for performance-driven applications requiring increased torque capacity and faster shifting. This kit features ACT's popular Heavy Duty pressure plate, which utilizes a proprietary diaphragm design to maximize clamp load while reducing deflection. Every diaphragm undergoes a specialized four-stage heat-treating process to ensure consistent pedal feel and long-term durability.

• ZM4-HDG6 Kit Components: Includes a Heavy Duty pressure plate and a 6-pad spring-centered race disc.
• Precision Engineering: Pressure plates feature precision cover stampings for improved rigidity and consistent engagement across the service life.
• Race-Ready Disc: The 6-pad ceramic race disc offers high heat capacity and faster shifting, making it ideal for aggressive driving and larger clutch sizes.
• Enhanced Strength: Spring retainers use wraparound windows and thicker stampings to provide superior spring support and reduce stress concentrations.
• Torsional Damping: The spring-centered hub is designed to properly damp vibrations, protecting the drivetrain even under harsh conditions.

Please note that while this kit provides rapid gear changes and high strength, engagement will be significantly harsher than a factory unit. This product is backed by ACT's one-year limited warranty.
