Great write up, I enjoyed reading your analysis and thoughts.

It seems you have the convertible version?

How is the chassis rigidity? Any flex or creaking noise at the base of the windshield? Any creaking from the top roof panel?

I ask because I had a C7 Z06 with Z07 package and that car creaked and groaned at the base of the windshield, top of the A pillars and on the targa roof. When I removed the targa roof the noises were quieter at the top but worse at the cowl. I think that car’s chassis wasn’t the stiffest, and the Z07 suspension was way too stiff for that car, so I constantly winced at every driveway, parking lot entrance, and exit.

This guy fixes rattles.
