18x9.5 +30 with 265/35 KU36's on the rear will rub on an unrolled guard, But only on Big bumps. If you use a +35 it will be fine. KU36 are a good tyre, I ran at Queensland Raceway with them. The only problem with them is they're a bit hopeless in the wet. These are my race wheels, They are 18x9.5 +30 all round.
