indeed, that's one of the reasons why the t/a so far has posted better grip than the z06.
T/A 2.0 1.21 g's (road and track) http://www.roadandtrack.com/new-cars/reviews/a6450/2015-road-and-track-performance-car-of-the-year-at-the-motown-mile/
Z06 1.19 g's (car and driver) http://www.caranddriver.com/chevrolet/corvette-z06
also the viper weighs 134 pounds less than the vette giving it a power to weight advantage http://www.torquenews.com/106/video-shows-viper-ta-stomping-2015-corvette-z06-over-and-over
I stand by my previous statements that the Viper T/A 2.0 will indeed give the Z06 a run for it's money, and perhaps even come out on top.
