The important part is teaching the kids about basic physics and good sportsmanship. Weight in the nose, careful alignment, polishing the wheel races with toothpaste to reduce drag, very light lubrication, areodynamically neutral. Like a whale shape.

I remeber a father who got kicked out for placing magnets in the nose of the car.
The starting gates were steel and when they dropped it pulled the car forward, giving an unfair advantage. Great. Some asshat teaching his kid to be a POS. Good lesson.
