I wouldn't get those...spend a little more and get the Shelby American Racing Antrachite Bullitts from www.Tirerack.com ...my rear tires in the pics are nitto 555dr 305/45/18 on SARs 18 X 10 riding on Eibach Pro Kit.
I would suggest going to a 18 X 10 rim in the rear...that's what i did...made a big difference and now I am able to run Nitto or my Mickey Thompson DRs in 305/45/18s
feeling alot better, thanks. i saw your post...my grille was the same way...i just lined up one side and redrilled the other side...didn't feel like fighting with anyone...lesson learned about street scene.
