I'm kind of curious if i would have to add any spacers to my 03 GT. I bought a set of 2003 cobra rims that are 17x9 with a 6.02" backspace (+26mm offset) and 17x10.5 with a 6.85" backspace (+27mm offset). I will be running 255 40 zr17 for the front and 315 35 zr17 for the rear. please let me know if you need spacers or not.
