Precision cut Stock Car pine derby Racer with a sleek aerodynamic design. This car is pre-drilled with 3/8" weight holes in the back, so you can add Tungsten Cylinder or Zinc Round weights. You can paint this car as is...or give it a light sanding to round off the edges... or have fun making new cuts to modify the design. This is a pine block with axle slots that conforms to all rules. The approximate weight of this car is 2.8 oz, plus or minus .3 oz. You will need about 1.5 to 2 oz extra weight. Just insert cylinder weights and cover the hole with wood putty for a clean, finished look. This is a car body only and does not include wheels or axles. We did the hard part, you have fun painting and decorating!
