It's nuts at that event. Basically when you're on the highway at night and you see headlights behind you lift, just get your ass over to the right before they mow you down doing 185. Those UGR G's were trapping 160+ last year, probably higher this year.
I'd give the AMS GTR the 1320 advantage, and the URG G's the highway roll. That AMS car came out of the hole like a raped ape all day when I was there. Respectable.
