ACT HD Performance Clutch Kit - Honda Civic Type-R FK8


- +


The 10th Generation Civic Type R is the ultimate Honda-lovers goal. Already responsive and powerful as delivered, this latest platform is being explored for serious transformations in power output. As those improvements surpass the capabilities of the OE clutch components, ACT is again stepping up to provide the latest clutch developments - just as Honda drivers have counted on for over two decades.

HC12-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.
