The HC10-HDR6 pairs ACT's Heavy Duty pressure plate with a 6-pad rigid race disc for the Honda Civic Si and related Accord/Integra platform. The Heavy Duty pressure plate uses an exclusive diaphragm design to raise clamp load and reduce deflection, with a four-stage heat-treated diaphragm and precision-stamped cover. The 6-pad rigid race disc uses high-quality ceramic friction material with a heat-treated chrome-moly hub; the lightweight, rigid design allows quicker shifts and smooth service, though engagement is harsher than a sprung disc.

FAQ
What does a Heavy Duty pressure plate change?
ACT Heavy Duty pressure plates use an upgraded diaphragm design that raises clamp load roughly 20 to 50 percent over stock, which reduces slip and extends clutch life.
What is a 6-pad rigid race disc?
It uses ceramic friction material on a rigid, lightweight hub rather than a sprung damper, giving quicker shift feel and more heat capacity at the cost of harsher engagement than a street disc.
Which platforms share this kit?
Per ACT's fitment data, the HC10-HDR6 covers the Honda Civic Si and Accord Sport along with the Acura Integra A-Spec for the model years listed in the vehicle applications above.
Is this kit suitable for a daily-driven Civic Si?
The rigid ceramic race disc gives harsher engagement than a street disc, so it's best suited to a car used primarily for track or aggressive driving.
