I really like my SS, but have put a lot into it (suspension, bigger wheels and tires probably made the biggest difference). I have a dozen track days under my belt and so am no expert at this. I have no idea how well it would run against those in the red or black run groups. Will hopefully let you know in a year or so
With a supercharger, my car smokes. Power to weight ratio similar to a Z06. Had it out once at Summit Point and was very happy with it, although the weather was cold and the tires weren't gripping all that well. I don't think I will have any problem keeping up with the Vettes at VIR. Honestly, at my level it is more driver than car and the driver still needs more upgrades.
I got the Camaro in part because I need to take kids to school in it. In 5 years I will probably upgrade to a 2 seater. But for now I am having an absolute blast in it.
