Baga Alore.bg ACT 1990 Honda Civic Sport Race Sprung 4 Pad Clutch Kit. HC4 SPG4 kit features a Sport pressure plate for a nice upgrade. ACT Sport 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 4 pad spring centered race disc features a spring center construction to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4 pad spring centered race disc, engagement is harsher, but shifting is faster. ACT's 4 pad spring centered race disc is well suited for smaller disc sizes in smaller engines.
