considering getting new wheels for my model s to make it feel new again. what is the WIDEST front wheel that someone has fitted successfully? I know the stock size on my car is 19x8 et 40. I know that several have fit 21x9 et 35 in the front and 21x10.5 et 38 in the rear. I was considering getting 20x9.5 et 40 in the front and wasn't sure if it would fit. Thanks!
