The ACT HD/Race Rigid 6-pad clutch kit for the 1999 Porsche 911 pairs a heavy-duty diaphragm pressure plate with a 6-pad rigid race disc to deliver aggressive engagement and quicker shifts for racing or high-load use. The diaphragm design increases clamp load and reduces deflection while parts undergo a four-stage heat-treating process for consistency. The kit uses ceramic-friction pads, a heat-treated chrome-moly hub, and carries ACT’s one-year warranty.
