Straight out of a video game
This is a world-class racetrack with a barebones campground attached. I was lucky enough to arrive while a Porsche club was lapping the track. I got to watch the cars coming down the "corkscrew" turn. It was just like Forza, but real. Phenomenal.
The campsites are on the expensive side, and you don't get much. There is barely any tree cover or privacy. The ground is dry, dusty, and hard packed. Difficult to drive tent stakes in some spots. The only bathrooms available are porta potties (the one I used was clean), and the water provided at spigots is non-potable (arsenic contaminated). So make sure to bring plenty of drinking water.
Also note that campsites are assigned by the attendent in a systematic way, so you will not be able to choose your site and you will probably have neighbors.
