Alright anyone could help would be awesome. I have the z06 wheels. 305/30/19 rear tires... tested them with a 2in spacer.and still not enough. The tires are 12in wide. Wondering if 3in spacer would work?? Or any insight for the matter. Also 275/30/18s are going on front. Tires in front are 10in wide still need spacers for front aswell? Didn't test fit the fronts yet. Thx guys in advance
