I am getting ready to by some new mags. Would it be safe to have 3 1/2 inch backspacing on the front and back rims. was a 4 1/2 inch bolt circle standard on 69 camaros? i think i am going with the weld racing pro star wheels for my 69. 15x6in front and15x8's in the back.
This is how you measure backspacing. You put a flat piece of metal across the back of your wheel and you measure how far it is from the metal to the BACK of the mounting surface of the wheel where the lugnut holes are. In effect you are measuring how "DEEP" the wheel is from the "BACK" of the wheel. Thus a wheel with 4 1/2" backspacing (stock backspacing) WILL NOT be as deep from the FRONT part of the wheel than the same size wheel with only 3 inch back spacing.
HDOG. Try 225/60-15 on the front. You will be much happier with them.
