Note: First lap shown is my new PB, second lap starting at the 2:07 mark is from the Challenge session. I think it was good enough for 4th place in the S3 class.

Fun 2-day weekend at Sonoma Raceway with SpeedSF, and SpeedSF Challenge on Sunday. Mechanical + steering angle sensor problems took a while to fix, but I was able to get back up and running with the help of good friends. Tires were at heatcycles #11 and #13.

I clearly have some more work to do at Sonoma, especially turn 7. Turn 1 to 2 I also see opportunity for improvement. Turn 10 I feel a bit weird.
