ACT HD/Race Rigid 4-Pad Clutch | 2016-2018 Mazda Miata (ZM12-HDR4) ACT Clutch Kits & Flywheels

2016-2018 Mazda Miata HD/Race Rigid 4-Pad Clutch by ACT

ZM12-HDR4 kit features ACT’s most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT’s 4-pad rigid race discs are made with high-quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.
