This is the same Wilwood Pedalbox assembly that we include with a complete kit Mk4 Roadster. This kit can be used to upgrade/replace your existing Mustang pedalbox in a base Mk3 or Mk4 kit. The pedalbox features dual 3/4 bore master cylinders linked with a balance bar for brake bias adjustment and forged pedals. A stainless steel reservoir with lines and fittings is included, along with all mounting brackets and hardware. All parts for a cable clutch system (quadrant, firewall adjuster, cable, hardware) are also included, but the pedalbox could also accept a 3rd master cylinder for use with a hydraulic clutch system if necessary.
