Ok I know it has been posted to death but I must ask. What is wrong with 3.25" back space, the track would be wider with the same size tire as compared to a 3.5" wheel right? A 4" back space woud help keep larger tires under the fenders if tie rods and calipers clear, right? So why be held to just 3.5 back spacing? Thanks for the help. JL ???
