ACT 4 Pad Sprung Race Disc - 4224204 Interior 08-14 Subaru Impreza WRX STI4224204 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.
