which wheel and tire combo

[gtmuscle]

I know this subject has been gone over before but my specific questions are:

on a 2007 GT500 with H&R race springs and a BMR adjustable panhard bar will a 10.5 inch 20 wheel with a 45 offset fit in the rear fender without any modification?

I want t put a 315/30/20 toyo R888 on but I need to go with a 10.5 wide wheel and I want to make sure it fits or is a10 wide with a 40 offset be better fit.

The Toyo 888 runs a bit wide and would best be suited on a 11" plus rim. Michelin just released a sticky streetable/roadrace Pilot Sport Cup 2 in 305 30 20 that you may take a look at for better fitment on your 10.5's.

Try the 2004 mustang bullitt rims, super popular and they always look good!
