New PB (CW) at the SoCal 86 Cup Chuckwalla rounds a couple weeks ago. CCW day was 2nd place in Unlimited class (went slower than previous visit though) and CW day was 1st place (new PB by few tenths). Getting really close to sub2 times at Chuckwalla now with just minimal upgrades (and fast tires :p ).
Didn't notice much difference testing 5W-40 weight oil, compared to 5W-30.
CCW lap of 2:01.146
CW lap of 2:00.688
