mattm:The reason that are so concerned with where the car is parked/located is that we get three runs at each course. We need the car and tires to be at their optimal performance level the minute the car hits the course. So dirty or coated tires are not something we can clean off with a warm-up lap or practice session.
Also... *NOT* bringing the dirt out onto the course for those three runs.
