After around 13 years of going to thunderhill, got down from a 2:35-ish in a miata to a few 2:00 in an mp4-12c (ok, took lots of laps of training, and a few car upgrades :)
Having a couple of radicals to follow and entice me to be faster probably didn't hurt :)
Thanks to Nico Rondet for the expert coaching and taking me down to 2:00 from 2:03.
Lots of wind courtesy of the "you must have your windows down policy", sorry, and yes the lap is cut a portion of a second short due to video editing (sorry), but I took the time in 3 locations, it's 2:00:xx, honest :)
(my lap timer with 5hz GPS said 1:59:70, but the video doesn't support that, so I'll go with 2:00:xx).
