We will time each run then display, and or announce your time. Remember, smooth is fast. There will be penalties assessed for hitting cones or missing the stop box. There are light poles in the zMAX lot and the course will be designed to minimize any chance of contact. Nonetheless, be sure to walk the course beforehand and be aware of where you might end up if you accidently miss a turn. We will have removable window markers on-site. You will need your ID # on the window so we may score autocross.
