C7 Z06 at COTA slicing and dicing through a bunch of traffic, 2:21

My first trip to COTA, what an amazing track. Car is my daily driven Z06 with a cold air intake, R7s and good brake pads. That is it otherwise bone stock the way I drive it everyday! I think it has a 2:19 in it after watching this video I see some areas I can pick up a lot of time. Day started off cold and wet so I only got 3 dry sessions. Morning sessions were interesting to say the least This was a track day, so wave by's were required. That is why I few times I got along side somebody then lifted and waited for the point by. I got in trouble earlier in the day O:-)
