My 87 IROC has been converted to 1LE brakes. The rear calipers are PBRs. I am trying to get the right fitment for a set of Bogart wheels and recently saw pics of a 4th gen car with these wheels on it. Is the wheel-to-caliper clearance the same on the 4th gen vs. 1LE 3rd gen? I have been under the impression that the rear would be identical, but am not sure about the front. What are the similarities/differences between the two setups relating to wheel clearance issues?
