what would the correct offset for the front and rear for a set of 17x 9.5 zo6 wheels? thanks

 

A 17x9.5" wheel will fit on the 4th Gen with no rubbing, as long as the offset is in the range of 45mm - 56mm. I've seen some people run as low as 38mm, but that puts the edge of the tire very close to being outside the fender.

The data I have indicates the Z06 17x9.5" wheels have a 54mm offset, so they will be fine.

 

Please shed some light on this for me. I want to put 17 9.5 w/ 285/40/17 on all corners. If I put 45mm backspacing vs 56mm, what would the diff be in looks(FITTMENT). Sorry, dont know too much about that.
