Ok, let's say the rules say "you must have 4 wheels",  but rules say not all four need to touch the track / ground and the rules don't specefy a minimum size or weight for the wheels.
How about a Hot Wheels car wheel for the fourth wheel? No weight to speak of and minimal air drag due to size.
Ok, maybe this is a stupid idea. Thoughts?
