No the gopro was not working for the tire blow up. To bad because it would have been a cool vid. It happened right at worst time. 115 mph in the middle of the banking corner. I was able to keep it under control and just pull off with out any spin. It happened Sunday morning so I raced with the kart looking like this.

Notice no more large rear wing and instead a diffuser wing behind the bumper. Trying to keep downforce but reduce drag. It seemed to work quite well.
