What are the dimensions of a go-kart track?

I assume your talking about a drag racing track, no exact answer can be given because each track differs from one to the next as far as approach, and shut down area go, the only thing constance is the length between the timing lights, for 1/4 mile drags its 1320 ft., there some who race 1/8mi. If your referring to other types of tracks, they also vary, you have oval, d-shape, paperclip shape, road-course, baja-1000 that goes for 1000 miles, all tracks differ in length an width and function. Again in any racing, there is no length (except in drag-racing, light to light) or width that is exact.
