I know the best/largest fitment are 19x8.5 and 19x9.5 respectively. If i were to put 20x8.5 all the way around was are the negative side effects, because I know there will be some. Will 19's fill the fender well up pretty good. Basically are 20's to big or will they rub or make the car not accelerate as quick.I know it should have 19's, but I want to know what the side effects re of 20's
