Nice driving! I'm incredibly jealous.
This is the perspective I've been waiting to see...so far my only on-track experience at CoTA was a slow lap in an X5 when it was under construction and a track run before the F1 race. Can't WAIT to get out there in the M3.
Seems you didn't have any trouble with Turn 19...I was surprised to see so many cars in F1 practice/qualy go off there.
I've been so impressed with the facility and the track. And the track-day setup looks awesome. I bet it was a blast!
