The ACT SB11-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular street disc, built as a conversion kit for Subaru's 230mm clutch. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life, with every diaphragm heat-treated through a four-stage process and a precision-stamped cover for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for better heat transfer, plus a steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action.

Pressure plate bolts included (M8-1.25 x 16mm).
