but can't fault GM for that. they chose a qualifying tire for max lap times, rather than something that can handle a wet track as well. The cup2r according to michelin is good for about -1.0 second for every mile of track compared to the cup2

Trap speed is usually a direct correlation with respect to HP / weight, so while the Corvette makes more HP it also carries more weight. Also the standard GT3 does not have the downforce of the ZO6, granted this is not an issue at launch but once speeds get into triple digits it becomes a factor.
