Yeah, I did run a 57. I was surprised as none of my laps felt that good to me where as other ones later in the day felt awesome, but weren't as fast.
I think I remember your car. Had an ESS or EAS plate in the rear?
Haven't had a chance to run through the video, but I'll let ya know. Had some good battles with I believe one of the instructors (Jordan?) in Josh's car and some other people.
