considering the improved suspension, grip and more power that the zo6 has, it would at least give the porsche a run for its money.
i'm not going to argue it, b/c i've not driven the 996, gt2 or zo6...
so i'm speculating.
however, if the c5 is found to be considerably slower in the hands of capable drivers on shorter road courses, it only makes sense that over a longer course, like the ring, that the zo6 would make a considerable gap b/n itself and a c5.
and i'm not claiming it's as fast or faster or anything than a porsche...
i'll wait for the numbers to show up there...
