The ACT HD/Race rigid 4-pad clutch kit for 1991 Porsche 911 pairs a heavy-duty diaphragm pressure plate with a 4-pad rigid race disc to support spirited driving and track use in smaller engines. The pressure plate uses an exclusive diaphragm design and four-stage heat treating for increased clamp load and consistency, while the ceramic-faced rigid disc and heat-treated chrome-moly hub favor quicker shifts. ACT backs it with a one-year warranty.
