Wow, the test and tune that WWSCC ran at Shelton on Saturday was really awesome. I think about 25 drivers showed up, so two run groups of 12 or so drivers. Just run continuously for 80 minutes, one side of the track is a figure 8 skidpad layout, the other side is a massive slalom. Just pick whatever side to run on and go. I did around 10-15 runs per side, more on the skidpad although it was much harder on the brakes.
In the afternoon they put it all together for about a 60 second run. I recorded 9 runs but I know I missed at least one because the camera was derping.
Biggest problem was heat soaking everything. Times would start to go up and then you just had to stop the car for five or ten minutes.
