The ACT NZ1-HDSS HD/Perf Street Sprung Clutch Kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular Performance street disc for the 2003-2006 Nissan 350Z and INFINITI G35. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design to increase clamp load and reduce deflection for longer clutch life, with every diaphragm undergoing ACT's four-stage heat-treating process. The Performance street disc uses premium organic friction material with high copper content for better heat transfer, plus steel-backed lining for greater burst strength and durability, with reduced marcel for faster shift action.
