Well I found out tonight not to have 4 adults in my car with 18" wheels and stock suspension. It looks like I'm going to be getting some ground controls pretty soon.

What springs are you running? I have H&R springs with 18x8's, it rubs a little with four people, but I can live with it....I don't have four people in my car everyday.
