Just a thought for all the tuners/shops out there, as I read about vibration/drone/buzzing/etc in relation to exhaust, oil coolers, etc. Has anyone tried to fab some way to mount some accelerometers to various locations of the car and establish a baseline via an oscilloscope or some other method? That way you could build a database of sorts (I realize that would take awhile, but hey, you have a common platform be it Z or G), but the payoff, IMO, would be huge by eliminating know locations of vibrations (drone, buzzing, etc.) before they would occur. The biggest investment would be time, I imagine. I'm a jet engine mechanic, vibrations are a big deal to us lol. Anyway, just a thought
