ACT Advanced Clutch XT/Race Sprung 4 Pad Kit Z65-XTG4

If you’re looking to maximize the performance of your 1986-1992 Mazda RX-7, the ACT Z65-XTG4 is your go-to clutch kit. Designed specifically for the most demanding drivers, this kit features an Xtreme pressure plate that elevates your driving experience, whether you're on the street or the track.

Why Choose the Z65-XTG4?

The heart of this kit is the exclusive diaphragm design of the ACT Xtreme pressure plate. This innovation increases clamp load while reducing deflection, which ultimately extends the life of your clutch. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring it can handle the heat and stress of high-performance driving.

With the 4-pad spring-centered race disc, you get a clutch that’s not only robust but also effective in dampening torsional vibrations. This means quieter operation and enhanced reliability, even under extreme conditions. The spring retainers are engineered with wraparound spring windows and thicker stampings to provide extra support, reducing stress and increasing durability.
