The ACT PO1-HDR6 heavy-duty 6‑pad race clutch kit for the 1991 Porsche 911 pairs ACT's Heavy Duty diaphragm pressure plate with a rigid 6‑pad race disc to increase clamp load, reduce deflection, and enable quicker shifts. Diaphragms undergo a four-stage heat‑treating process; the race disc uses ceramic friction facing and a heat‑treated chrome‑moly hub. Engagement is firm and better suited to larger clutch sizes; kit includes a one‑year warranty.
