19x9 +35 up front will fit, 19x9 +30 at the rear will be flush.
running 9.5 at the front might rub on the inside near the shocks when turning.
i would say 19x8.5 +35f, and 19x8.5 +30r would be the best bet.
consequently, 20x8.5 +35 should fit as well IF YOU RUN STRETCHED TIRES...225/35/20 or 225/30/20. but then you also run a higher risk of curbing your wheels. but like dayvers said..stretched tires are sexyyy
^^^ that is, keeping in mind that your car is already lowered. if your car is not lowered, then fitment and rubbing shouldnt be much of an issue unless you are running an insane measurement like 20x9 +22 all around hehehe
