The ACT ZX5-HDSS is a conversion kit that pairs ACT's most popular Heavy Duty pressure plate with its most popular Performance Street disc for the Mazdaspeed 3 and Mazdaspeed 6. The Heavy Duty pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life, with every diaphragm heat-treated in a four-stage process. Precision cover stampings provide rigidity and consistency. The Performance Street disc features premium organic materials with high copper content for better heat transfer and a steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action.
