Sport/Race Rigid 6-Pad Clutch Kit

The ACT HC4-SPR6 clutch kit pairs a Sport pressure plate with a 6-pad rigid race disc for 1990-1991 Honda Civic and 1990-1991 Honda CRX race applications. The Sport pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. ACT's 6-pad rigid race disc is made with high quality ceramic friction materials, and the chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 6-pad rigid race disc, engagement is harsher, but shifting is faster. The 6-pad rigid race disc is recommended for larger clutch sizes to absorb more heat. Part number HC4-SPR6 (as listed in legacy data; official verification pending).
