Try to get the car to maximum weight (5oz). Most of the weight should be at the back. 3/4 of an inch forward of rear axle should be center of gravity (the car will balance at this point). Sand 600+ grit sandpaper to the wheels to remove imperfections. Polish the axles to a mirror finish. After cutting and sanding the body, bake at 200 degrees for about 2 hours. This will remove any moisture from the wood so you can put more weight at the back. I hope my son is not racing your sons! Search the web for design ideas. There are site out there to purchase some of these tips.

Get yourself a long piece of fat piano wire drill a hole near the front of the car the size of the wire pass it through so that it will block the other cars then when setting up at the starting line spring the wire out and in front of the other cars so all they can do is push your car faster

Keep it as close to ten pounds as you can, go for an aerodynamic shape (a wedge works well) and make sure the axles are perfectly straight and aligned, and keep them as lubed as possible.
