This is the same Wilwood Pedal Box assembly that we include with a complete kit Mk4 Roadster. This kit can be used to upgrade/replace your existing Mustang pedal box in a Mk4 Roadster kit. The pedal box features a 3/4" front and rear 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. The pedal box could also accept a 3rd master cylinder for use with a hydraulic clutch system if necessary.
