I bought ATS spindles (added benefit of the tall spindle for handling-reduced neg camber gain)that allows C5 front brakes to be a bolt on 12.7" , and in the rear im using ls1 f-body rear brakes 12". this is not a bolt on kit because all the late model lines use metric bubble flare line whick have to be adapted IMO this whole swap including spindles($675) should be doable - with being resourceful and thrifty for under $1500 - kinda depents on how much you would rather figure out or if you want a complete kit and bolt it on,although bolt on leaves you with the stock suspension geometry but this is just my .02c
