To answer some of the questions I've been getting:
Wheels are all 18x8 with 4.5" BS. I wanted the same size on all four. However, the back wheels are in about an inch from where I want them, so I may end up with spacers. They have plenty of clearance, they just aren't as far apart as the front wheels.
Tires are all 255/55R18
Wheels are American Racing CL205, which is a variation of the Torq Thrust II.
Here's a couple more pics:
