JMK, here are my personal videos from Mid Ohio and Gingerman - didn't realize you were in Chicago like me.
Remember, this is from my s2000 in TTC
NASA Nationals - almost a national champion
Gingerman the day after NASA Nationals. 1:42.1 - .5 off TTA Record, 1.5 seconds or so faster than the TTB record, and 4 seconds faster than TTC record, all in TTC trim. Gingerman doesn't pull top level drivers, so I don't count lap records there with as much regard.
