ACT 4-Pad Sprung Race Disc - 04+ STI

4240518 is a 4-pad spring-centered race disc made with high quality, ceramic friction materials. The engagement is harsher, but shifting is faster. The heavy duty torsional dampening springs are stronger, in most cases, than standard springs and are provided in the best sizes and spring rates to suit the application. The race disc features a heat-treated spring steel drive plate and is well-suited for the smaller disc sizes in smaller engines.
