From the desk of ACT:
ZM4-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability. Description: HD/Perf Street Sprung Torque Capacity (ft/lbs.): 275 (46% over stock) Disc Type: Street Disc Pressure Plate Type: Heavy Duty Product Weight (lbs.): 13.4 HPMotors has had great results with ACT products in both our street car and race applications, naturally aspirated or boosted, across several makes and models of vehicles. This particular set-up offers a great balance of drive-ability and ease of use while also being able to handle higher levels of torque. |

ZM4-HDG6 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 6-pad, spring-centered race disc features a spring-center to properly damp torsional vibrations and resist failure under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 6-pad, spring-centered race disc, engagement is harsher, but shifting is faster. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat. Description: HD/Race Sprung 6 Pad Torque Capacity (ft/lbs.): 355 (87% over stock) Disc Type: Race Disc Pressure Plate Type: Heavy Duty Product Weight (lbs.): 13.9 HPMotors has had great results with ACT products in both our street car and race applications, naturally aspirated or boosted, across several makes and models of vehicles. This particular set-up offers a compromise for high boost/high torque street car applications. Pedal feel will still be close to stock, but clutch engagement will feel much more quick and direct. Stop and go traffic can get annoying. We don't recommend this kit unless you have the power to need it. |
