ACT 17-19 Honda Civic Type R HD/Race Rigid 4 Pad Clutch Kit (HC12-HDR4)
The 10th Generation Civic Type R represents the pinnacle of performance for Honda enthusiasts. Already renowned for its responsiveness and power, this platform is quickly becoming a favorite for serious power upgrades. As these modifications push beyond the limits of the original clutch components, ACT once again delivers advanced clutch solutions—just as Honda drivers have trusted for over 20 years. The HC12-HDR4 clutch kit features ACT's highly regarded heavy-duty pressure plate. This design incorporates a proprietary diaphragm to enhance clamp load, minimize deflection, and extend clutch life. Each diaphragm undergoes a meticulous four-stage heat-treatment process to ensure unmatched performance. ACT pressure plates are engineered with precision-stamped covers, offering superior rigidity and reliability. The kit also includes a 4-pad rigid race disc, crafted with premium ceramic friction materials for exceptional durability. Its chrome-moly hub is heat-treated for added strength, while the lightweight and rigid construction promotes quicker shifts and seamless operation. While the 4-pad rigid race disc delivers more aggressive engagement, it also allows for faster shifting—making it ideal for smaller disc sizes in compact, high-performance engines. For enthusiasts seeking peak performance and reliability, the HC12-HDR4 kit is designed to handle upgraded power and spirited driving demands.
