Maximize your potential energy while giving your car a retro-futuristic look! Weight distribution is crucial on fast Pinewood Derby cars. These tungsten domes let you tweak your weight distribution by adjusting their mounting location and orientation. For a conservative center of gravity, arrange the weight so it runs longways on the car. For a more aggressive car, turn the weight so it is oriented sideways.

These domes are heavy, coming in at 3.50 oz. Therefore, for most races, your car body (including paint, etc.), wheels, and axles must weigh no more than 1.50 oz. This may require removing a significant amount of wood from the Derby block.

For installation, drill a 3/8”-1/2” hole at your desired location (measure to verify) and insert the weight’s post. Use glue or double-sided tape under the edges of the weight to ensure it is firmly affixed to the car body.

PLEASE NOTE: These weights are NOT compatible with the Turbo Derby CNC bodies. You will need to make your own car body from an approved Derby block.
