Laguna Seca -  

I don't normally post PB videos, but I feel like a sub 40 at Laguna Seca is such a big milestone that it deserves its own video (yea yea I know everyone's faster post repave but still). I also included the catalyst's optimal lap to see what I can already do with the current setup, and it also shows that the PB lap did like 2 corners well. There's still so much room for improvement that I'm starting to believe I can get a 37 one day.
Date: 11/26/2023 (post repave)
Weather: low-mid 60s, dry
Host: SpeedSF
Group: slow advanced
Tires: 4th day (cycled out and no tread left)
Brakes: pads very thicc but front rotors have deposits
Other: alignment knocked off from a prior track day (lost camber on left rear)
Driver: tired and sick of laguna already (PB lap was the very last hot lap of the day)
