ok i have a set of center line convo pros. currently they are 15x8.5 with 3 3/8 backspacing and stick out way too far. center line's website is saying though that for 15x8 in wheels their maximum backspacing is 4.5 and for 15x8.5 wheels their maximum backspacing is 5 inches. is there anyone on here running a set of center line wheels on their fox and could shed any light on the subject?
