We raced at Kirkland Ranch Center of Innovation. Their new building is pretty spectacular. The parking lot was smooth. There are high curbs which would have punished any mistakes. The reflectors embedded in the pavement shook the car when hit with a 120 psi tire. In the first race video, I delay getting on the power exiting the chicane to avoid one.
In both races, the last turn (first race) or first turn (second race) added to the challenge. Fast, sweeping, downhill and off camber.
