The ACT HD/Race sprung 4-pad clutch kit for 1991 Mazda Miata centers on a Heavy Duty diaphragm pressure plate and a spring-centered 4-pad race disc for robust engagement. Diaphragms undergo a four-stage heat-treat process and precision stampings add rigidity. The spring-centered disc damps torsional vibration and supports faster shifting with increased strength. ACT backs it with a one-year warranty.
