I want to put 20x8.5s on my 98' xj8. The thing is I want a more flush clean look with the fenders. What's a good offset for no rubbing and looking flush

 

This works for me perfect. 18x8 offset 20

 

thanks!

 

Could anyone share the actual front spacing and backspacing on the XJ(R) 308 itself? I believe that would solve so many questions regarding what wheels and tires would fit and what offset would be required. I'm desperately trying to find that information.

 

I can tell you a 1-2 offset on 18x8 contacts on every corner with 8.5 and a 255 x30 or 35 ratio for15-20 offset seems about right
