Description: Enhance the performance of your Ford Mustang GT with the FM4-SPSS kit from ACT. This kit features a Sport pressure plate designed to provide a noticeable upgrade in clutch performance. ACT Sport pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for unparalleled durability. Precision cover stampings ensure rigidity and consistency.

Paired with the pressure plate is ACT's Performance street disc, the most popular disc purchased. These discs feature premium organic materials 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, these discs complement the ACT pressure plates perfectly. They provide quiet operation along with increased strength and reliability.
