im going to get some convo pros for my 71 camaro . i am going to get 15,s all round and im thinking 8,s on the back and 7,s on the front but if i can get 7.5,s on the front ill do it. i jst dont know what backspacing the 71,s can take.i only just got into camaros. its a weird system but in the convo pros the 7,s and the 8,s both have 3,3/8 back space but the 7.5,s have a 5 inch backspace... kinda weird but if i can fit the 7.5,s in the front i might as well do it dont you think to get as much of those sexy looking ribs on the wheel as i can. anyone got any info????
