i got 18's sittin in my garage waiting to be wrapped in rubber...they are 18x7.5 with a 48mm offset....the 45 offset might rub the outside lip...since ur not lowering it, shouldnt be that bad....the 17x7 with 40 offset will be even worse...i suggest tryin the 18s and if anythin cut away at the wheel well lining so there wont be any rubbing
