First proper test day at Buttonwillow CW13! We are prepping for Global Time Attack Finals coming up in November. Amazing day with Socal Drivers Club! Don't mind the map and start/finish line here, unfortunately I had the AIM set on CW17 and not 13. This lap is a 1:48.9, my morning lap in cooler temps with worse driving was a 48.80 and we backed it up again after this lap with another 48.93. Tires were about 8-10HC on them. Looking at the data and watching the lap, there is a 46 in the car for sure. Just need to put it together!
