and remember in my video 997GT2 vs Z06, the Vette has 520/530hps, this Z06 is not stock!!
We've already gone over this argument. Autocar is terrible at driving LHD cars with stick shifts. They constantly miss gears and shift terribly, and cannot get the launches down either. Just look at their video with the Z06 vs the GT2. Everyone still knows the ZR1 is faster than the GT2, it's just a simple fact, don't try to ignore it or dispute it.
The small chance the porsche has is getting a better launch (especially with its engine in the back) but thats about it... and its not enough, it WILL eat dust as speed increases.
