ACT 16-17 Mazda MX-5 Miata ND 4 Pad Sprung Race Disc4224505 1 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.
