The ACT HD/Race clutch kit for 1991 Mazda Miata pairs ACT’s Heavy Duty diaphragm pressure plate with a 6-pad rigid race disc to deliver increased clamp load and quicker shifts. The pressure plate is heat-treated in a four-stage process for rigidity and consistency, while the chrome-moly hub and ceramic friction material on the disc improve heat resistance. Engagement is firmer for fast shifting; kit is backed by a one-year warranty.
