My .02 cents would be to upgrade the suspension.
V6 Camaro, regardless of any other upgrades, needs to beef up its rear sway bar. Go ahead and get a front and rear set, but the back one is way too weak from the factory. They're an easy install, and will make a believer out of you the very first drive!
And the back sway doesn't just improve weight distribution when cornering- it also keeps the back end planted under acceleration...
