ACT Extreme Race Sprung 6 Pad Clutch 2004-2021 STI / 2007-2009 Legacy GT Spec B

The SB10-XTG6 ACT Extreme Race Sprung 6 Pad Clutch Kit is designed for high-power drivers demanding aggressive engagement and long-lasting durability. It features an Xtreme pressure plate with an exclusive diaphragm design that increases clamp load, reduces deflection, and maximizes clutch life. The 6-pad spring-centered ceramic disc dampens torsional vibrations and maintains reliability under harsh driving conditions. Monoloc—a one-piece, chrome-moly steel retaining system—ensures uniform loading on the bearing and pressure plate, improving alignment and release mechanism longevity.
