Hmmn. Someone on Camaro5 did a photoshop with the perfect wheels IMO, but these are really close to what I like. I guess I would buy a dark grey one sight unseen before buying the wheels though. Once I saw it I would determine if the windows were tinted dark enough. I would lose the GM badges day 1. Then replace the bowtie on the front with an SS emblem ASAP. Aside from that I don't know. I think it's near perfect. I can appreciate the car in the photo, but I'm not that much of a showboat. I would force myself to sell it within a year and a half while it's worth something too.
Put on a true ram air intake system, headers, borla exhaust, larger spoiler on the back, tint, dual rally stripes running the whole length of the car, chrome wheels (no bigger than 19s), and have the computer reflashed to free up the hidden ponies GM left in there.
