I did a 1:59.108 in HP Autowerk's 335i on absolutely shot Yokohama AD08's. That car would be in the :57's with some good fresh street tires.
Jeff, I finally got my ass out to Buttonwillow. I kept your estimated lap times in mind all the time.
Anyway, I did everything I could, but the quickest lap I did was 2:11.8xx. I think I can get to 2:10, or maybe 2:09 if the ambient temp wasn't in the mid-high 90s. I'll post up the video tonight or tomorrow.
