The ACT SB11-XTSS kit pairs a Xtreme pressure plate with a Performance Street organic disc for street and light track use on the WRX platform. ACT's Xtreme pressure plate uses an exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life for the most demanding drivers. All diaphragms go through a four-stage heat-treating process, and precision cover stampings add rigidity and consistency. Xtreme pressure plates increase clamp load by 50 to 120 percent over stock. ACT's Performance Street discs are the brand's most popular disc, using premium organic friction material with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. A reduced marcel provides faster shift action to complement the pressure plate, with quiet operation and increased strength and reliability.
