Haven't driven Chuckwalla CW in over two years, but finally went back over the weekend.
Tires were on their 3rd day and I struggled finding front grip all day. Best lap was my very first, but throughout the day I made changes and eventually went back to the morning setup and ran two more 1:54's. Not a very exciting lap. I found that keeping it in 4th gear for most of the lap was the fastest way around for me.
