What is the main difference between this race disc and a standard clutch disc?

The 4-pad spring-centered race disc has a harsher engagement and is designed for faster shifting. It also uses a spring-center construction to properly damp torsional vibrations and resist failure under harsh conditions.

What makes the ACT Sport pressure plate different from a stock one?

The ACT Sport pressure plate uses an exclusive diaphragm design to increase clamp load and reduce deflection. All diaphragms undergo a four-stage heat-treating process for improved performance and durability.

Does this clutch kit include all the necessary hardware for installation?

The manufacturer description lists the ACT Sport/Race Sprung 4 Pad Clutch Kit (TC1-SPG4) as included. It is recommended to consult the manufacturer's installation instructions for a complete list of required hardware and procedures.

Product Details

TC1-SPG4 kit features a Sport pressure plate for a nice upgrade. ACT Sport 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 4-pad spring-centered race disc features a spring-center construction to properly damp torsional vibrations for quieter operation and resist failure even 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 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.
