I agree with everyone here, never 20's..it will look like s**t and ride even worse. I have 18's on mine, but they have to be the right wheel in order to look appropriate imo, mine are all black saleen replicas, but because they blend in with the black rubber, it makes them look a tad smaller and...it works...I think lol. A big flashy 18....just not my cup o tea....ultimately...it's your car, don't be persuaded from a wheel you like by guys on a forum who will never see the car in person
