I know everyone likes to go bigger, but these were super cheap and I think they look pretty good. They're 2009 CTS premium full polish wheels, 18x8.5" 48et. They went right on and widened the tires a little. I'm waiting for the center caps I ordered. The Caddy caps were way too bling-y. I got these wheels for 300 bucks of C/L and paid another hundred to get them swapped out. Big step up from the steel wheels with detective hubcaps.
