First time at Buttonwillow with SpeedVentures on Sat, Dec 17th.
Track was setup in 13CW config.
Dense fog throughout the day and damp track, but probably dry by this time.
35min into the last session of the day, I went for one more hot lap before calling it. There was noticeable brake fade by this point so I was more conservative with my braking zones.
