Talking about the cradle moving around, check out this video! This is the reason a lot of us have installed solid subframe/cradle bushings, to get it all tightened up. Makes a huge difference. Some of the guys then also went with poly diff bushings, some stayed rubber, me I stayed stock rubber, but solid cradle bushings. Welcome to the "5th gen" family. Another note on your searching, use google for what you are looking for, combined with camaro5.com, that will get you a lot of stuff that is on here. Good luck!
