hey guys. im having an issue with the cobra rear upgrade on my 90 gt. i know this issue has been discussed somewere else but cant seem to find it. my caliper brackets are rubbing/scraping on the rotor only on the outside of it. i kept my existing calipers from a 95 gt but just switched the caliper bracket to a cobra one, and im using cobra vented rotors, cobra brake pads and north race car brackets. any ideas why this might happen?. im using moser axles if that makes any diffrence.
