I would guess that the ZL1 is the target for the '13 GT500. That being said, I bet it will be very close and who knows who will come out on top. As long as it is close, they will post the time. The reason I think this (even if it isn't as fast around as the ZL1) is that looks at the other cars around this time. I don't think anyone would mind having their car listed in that pack
