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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e*SPECIAL ORDER\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHonda Civic Type R \u003c\/strong\u003e(2017, 2018, 2019)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv id=\"newdescrRC\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeel:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLight to moderate pedal effort, aggressive engagement, increased gear rattle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLife:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eModerate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuality:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCarefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRecommended for race use only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eACT Difference:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e100% clamp load tested and dynamically computer balanced for smooth high RPM reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTorque Capacity (ft\/lbs.) 527\u003c\/li\u003e\n\u003cli\u003eTorque Capacity Over OE 71%\u003c\/li\u003e\n\u003cli\u003eDisc Material Ceramic\u003c\/li\u003e\n\u003cli\u003eFriction Surface Diameter (Inches) 9.4\u003c\/li\u003e\n\u003cli\u003eFriction Surface Diameter (mm) 240\u003c\/li\u003e\n\u003cli\u003eInput Shaft Diameter (Inches) 1.0325\u003c\/li\u003e\n\u003cli\u003eSpline Count 24\u003c\/li\u003e\n\u003cli\u003eDisc Type Rigid Race Disc\u003c\/li\u003e\n\u003cli\u003ePressure Plate Type Heavy Duty\u003c\/li\u003e\n\u003cli\u003eFlywheel Type Streetlite\u003c\/li\u003e\n\u003cli\u003eFlywheel Tooth Quantity 149\u003c\/li\u003e\n\u003cli\u003eFlywheel Mounting Hole Quantity 8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv id=\"newdescrLC\"\u003e\u003c\/div\u003e","brand":"ACT","offers":[{"title":"Default Title","offer_id":45062066929978,"sku":"actHC12-HDR4","price":1253.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0025\/9709\/3420\/products\/82edac7cad9f0284c344581eefec196e.jpg?v=1683140851","url":"https:\/\/www.kamispeed.com\/products\/act-17-19-honda-civic-type-r-hd-race-rigid-4-pad-clutch-kit","provider":"KamiSpeed.com","version":"1.0","type":"link"}
