I have looked at threads all over the web, and decided to give this a shot. I got a complete rear brake setup off a 01 Z28, and also had the rear brakes from a 06 Gto that I parted out to use ls2/t56...What I came up with was a low cost way to use left and right ls1 brake setups with Gto calipers and clear the staggered shocks. I used the ls1 parking brake setup with ls1 rotors/pads and caliper brackets...the Gto calipers bolt right up and clear with 1 1/2" between the right caliper and shock. just mock up at this point but now knowing it works I will get everything cleaned up/painted and get pads and rotors ordered.
