  Hints  
1.

The heavier your car, the faster it will go. If it is too heavy, your car will cross the finish line before the other car.

 
2. The lighter your car, the slower it will go. If your car is too light, it won't cross the finish line.  
3. Take serious consideration in the rotation of the wheels. Do they spin freely or is there resistance?  
4. Aerodynamics will be an important factor in the speed of your car.  
5. Your car must consistently cross the finish line in order to win the Derby.  
6. If you any advice or encouragement, please feel free to contact Lee Walton personally at his web site.
