Hi, I'm wondering if anybody has put aftermarket 18s on their track model... that are not "too expensive". I'm looking for a different look than the factory Rays, but a local wheel dealer told me I'm hard pressed to find anything under $900 canadian per wheel, due to the big brakes. Let me know if anybody out there has sub $400 U.S. per wheel on theirs... that fit properly. Any feedback would be great. I don't want to spend $4K Canadian until I go with 19s
