      Brake fitting in 15" wheels

      OK guys I have a question for you on fitting big brakes. So many of the aftermarket kits require 16" or bigger wheels for 12" rotors. GM put 12 " rotors on B body cars with 15" wheels. NASCAR requires 15" wheels and uses HUGE 6 piston calipers. Corvettes and early Camaros/Chevelle/GTOs used big 4 piston calipers in 14 and 15" wheels.Why the fit issues from the aftermarket?

      Saw a article in newest HotRod of a girl who made custom brackets to fit the larger Wilwood calipers and 11.75 rotors in 15" Chevy Ralley wheels.

      Why not kits using a bigger caliper/pad from Wilwood than the dinky Dynalyte? Baer's calipers are similar to factory GM 3rd/4th gen that aren't that tight in factory wheels.
