I have spent way more money and time chasing a vibration issue in my 05' Crossfire Roadster than I would like to admit to myself. My solution after dealing with this for years was to just buy a new 2SS Convertible Camaro.

I'm done jacking with my Crossfire. Time to sell it. That being said, I would like to get the vibration fixed before sending her off to the next owner. @Superfragl What did you use to make these measurements? That document seems a bit hard to follow. I may need to get an engineer to help me.
