I bought this car with the 5 lug and rear disc conversion already done. I have just recently noticed that the rears wheels stick out a bit more towards the rear quarters more than Id like them to. Car currently has 17" Bullits on it. Is there a simple way to correct this situation? Is it a known problem? If not, what backspacing of wheels would I need to make it look like a factory wheel? Im thinking of changing to black Bullitts instead of the Anthracite, so I might do that
