This is pretty insane. The GT3 is only .53 second per lap faster with a professional driver. Andy Pilgrim say's it best, regarding the GT3: "Simply put, less mechanical grip and the need for more rear downforce in the GT3 equals more sliding and longer slide-recovery times, and this would be more uncomfortable for average track-day warriors. I can say it's easier for me to go fast in the Z/28, and if I owned one, I'd sure go looking for GT3s to play with at any track day. If both of these are in my garage, it would be the GT3 for the street and the Z/28 for the track, every time."
DAMN!!!
