Get the most stopping power out of your Miata’s brake system using the 1″ bore Wilwood master cylinder kit. This master cylinder upgrade is made to work with modified brake systems utilizing larger piston area calipers. The kit helps reduce pedal travel while achieving solid pedal feel & modulation. Excellent upgrade for MX5’s that see heavy track use. Pair this kit with the master cylinder brace to reduce firewall flex, stiffen the pedal and improve hard braking performance even further.
Not compatible with MSM or ABS boosters.
