Just out of curiosity, what kind of feedback and coaching was everyone getting in car? And did you guys get a chance to go for a ride in other cars? I only had one person (other than the friend I came with) tag along for a ride, but my passenger seat is ALWAYS open to anyone. I can't guarantee a perfect run, but I can guarantee a safe return
I find the single biggest help (especially on a new track) is going for a ride in someone's car who has been out already so you can see the line without having to worry about what you're doing.
