well most racers on the club level have enclosed trailers and they put regular tool boxes like in car shops in the trailer they strap them to the wall in the back by the rear door. standard op really. now for the car auto cross guys don't know if they don't use a trailer they really are strapped for space if they bring slicks to the track. auto crossers don't need that many tools anyway. a jack and lug wrench hope this helps.
