I have a pair of 14" front brake rotors that I would like to install on my 2011 Mustang GT. I want to keep the factory calipers which gave been upgraded with new seals, pistons, brake lines, silicone brake fluid, etc. I upgrade the rotors to Power Stop drilled/slotted 13.22"; the factory size.Does anyone know where I could purchase the proper (extended?) bracket to mount the caliper in the proper position. I really don't want to go to a 14" conversion kit (rotor, bracket and bolts as they are ridiculously expensive. I just want more bite from the brakes.
