PB Lap Time - 1:56.9xx (had some traffic leading up to it, and also some slow downs in the middle and the end; so, could probably have made up another 2 seconds)

Second time tracking Sonoma, and also the second GR Day out there! NorCal GRC Club and 555 Engineering always help meets like this be as fun and exciting as possible, and SF Speed always puts on great HPDE events.

Decided to not run the last two sessions due to a random Crankcase code popping up (apparently even a stock air box will pop that code randomly lmao) and causing the dash to Christmas tree, so I think I missed out on some lower traffic and better conditions. But, that just means I have to come back out again soon!
