They look very classy personally i think if you lower it and get some different tires it will look fine with 18s ive seen it done with the cervinis kit

I like the wheels, I think they would look sharp on your car. However, I also like the foose nitrous. I guess thats not much help. I wouldn't worry about the performance issue, it's not like the wheels will turn our car into a honda civic or something. I wouldn't do 20's myself because of the performance issue, but then agian my car won't look as good as yours. Like everyone says make a plan for your car and work the plan. Style and good looks is a nice plan!
