What tire size u use? How is it on the road? If u load ur car, is there any tire rubbing in back? If I want to avoid this problem (on 11'' if is possible) what is the widest tire or mm at the back?
Post pic if u have!

 

17X11 Grand Sport wheels. 315/35/17. Good but would be better to have a dr if you have big power. Yes but if you roll the fenders and use the BFH inside the wheel well and grind down the bump stops it will be minimized. to avoid it do what I mentioned above or go 17X9 and 275s

 

315 is the ideal tire size.

 

I had it on my old LT1 17-9.5 315/35
Any pic for 11'' with 315/35/17

 

Here ya go. 315/35/17's
