My most recent run at Road Atlanta...a 1:31.1 in the Viper. It wasn't a great lap cause I got some wheel spin out of T7, but I'm starting to get more used to the car and the new camber settings helped some too. 
Conditions: Hoosier A7s, those amazing Carbotech brakes (XP20s front and XP12s rear), 70 degrees.
The track seems to be "going away" a bit over the past few years as I've noticed the lap times for the cars drop slowly, and it's pretty bumpy now, but still a blast to drive! Thanks to Butch Kummer and Mike Puskar for all your help!! Enjoy!
