We also Engineered a bracket so you can use Wilwood 4 piston Calipers on stock rotors for those on a budget.
The rear brackets in your performance kit look like the right ones. are they .75" thick? I have 12.2 inch rotors. It was slightly more than 6 inches to the center of the axle. Those wilwood calipers also look like mine. I would assume that if your brackets are .75 inch thick that they will work. If I measure those dimensions how long till you can ship?, and how much for the rear brackets with bolts?
