+45s might be a lil close to the inner suspension, but yea DEFINETLY get 35. In fact, you should probably get the +35s, then get OTG shim spacers for the rear. Youd be in good shape then. More flush than most, and looking good.
btw, I had Motegi's w/ the +45 offset wrapped w/ 215/35/18's and I rubbed on the inside. got the OTG shims and was golden. so, if you get the +45 offset, you will need the shims before hand or you'll shred your rubber.
now that I have the +0 offset, I rub on the outside. I said it before and I'll say it again - pay the money and get the rims you really want. that +10 - +25 offset range is slim plickins, but had I just got the custom JLines, it'd be Christmas everyday.
