Put new tires on front (275-35-19 Nitto Invo)... wobble went away....
Let us know how you like them, may go that route next time.
I'd hate to run that much pressure.
I am sitting at the Chevy steelership right I just traded the shelby off on a zo6 I hated the wobble that much.
I would advise against that tire on the Z06, it's not the car.
