The ACT ZM2-XTSS Xtreme Performance Street Sprung Clutch Kit pairs an ACT Xtreme pressure plate with ACT's most popular street disc for the most demanding drivers. The Xtreme pressure plate uses an exclusive diaphragm design to increase clamp load and reduce deflection, with every diaphragm undergoing ACT's four-stage heat-treating process and precision cover stampings for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for improved heat transfer and a steel-backed lining for greater burst strength, with reduced marcel for faster, quieter shift action alongside the Xtreme pressure plate.
