I have a 2013 mustang gt with brembos. I am looking into nitto nt05r radials. I'm going to get them on 2010 gt500 rims. I wanna know if I can go with 305-45-18 in the back? I know 285-40's will fit but I want some extra traction the 305's offer. Will they fit? This is just for track use only and they will not be daily driven on.
