Funny thing is I know three people with new Z06's, two manuals, one automatic. They all track them, and well. Even in FL none of them have overheated. It must take long sessions to make them overheat. I think I read that someone (may have been TSP?) was making cooling upgrades to stop any issues, if you had them...

Several things around this. First the "heat soak" issue seemed be largely related to poorly bled superchargers in the Z06. Second, the Z06s have additional transmission cooling that Z51's didn't (until 2016 MY), but somehow their transmission heat issues were assumed to exist in Z06s. Finally, most of the transmission heat issues can be avoided by not engine braking...which is a bad idea on the track no matter what transmission you have.
Remember, they track them all day long every day at Ron Fellows and they have never experienced an overheating issue. I asked while I was there.
