ACT 2019-2025 Mazda MX-5 Miata ZM14-HDSS Heavy Duty Performance Street Sprung Clutch Kit with Flywheel

Fits 2019-2025 Mazda MX-5 Miata and MX-5 Miata RF models across all trims including Sport, Club, Grand Touring, and special anniversary editions.

The ACT ZM14-HDSS kit is engineered for drivers seeking a significant upgrade in holding capacity without sacrificing street driveability. This comprehensive package includes the Heavy Duty pressure plate and a Performance Street sprung disc, specifically paired with a matched flywheel to optimize the ND2 Miata's drivetrain. The pressure plate features an exclusive diaphragm design that undergoes a rigorous four-stage heat-treating process, ensuring consistent pedal feel, reduced deflection, and maximum clamp load over the life of the clutch.

The included Performance Street disc utilizes premium organic friction materials with high copper content for superior heat dissipation. To ensure durability under spirited driving, the linings are steel-backed for high burst strength. These discs are designed with reduced marcel to enable faster shift action, complementing the increased precision of the ACT pressure plate assembly.
