The NZ1-XTSS kit pairs an ACT Xtreme pressure plate with ACT's most popular Performance Street disc, sized for the VQ35DE-equipped 350Z and G35. The Xtreme pressure plate uses ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and extend clutch life; every diaphragm goes through a four-stage heat-treating process, and cover stampings are precision-made for rigidity and consistency. The Performance Street disc uses premium organic friction material with high copper content for better heat transfer and a steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action, quiet operation, and increased reliability.
