2017 Corvette Z06/Z07 at HPDE at NCM right after the Bash. Had a session with John Heinricy yesterday, and he ran pretty quick laps in the car. I'm working on that line for a couple of sessions today to see where the time reduction comes in versus my previous line. Using Cosworth Tolls to evaluate the data, and it helps a ton. I'll get a video out on Cosworth soon.
