I would say get a pair of stock 19" that look like mini RS wheels or find a pie of RS wheels that a member is getting rid of. They are usually very cheap and look awesome on the car for the price. I have a 1LS and I plasti dipped a set of 19" aluminum wheels, slapped them on, and it's been like a whole different car.
All depends on how much you can spend. If on a budget go for the upgraded stock wheels. Best bang for your buck IMO
