Cylinder Flex Weights | 3 oz | Cuttable with Scissors

Pinewood Derby weights add mass to your derby car. This leverages inertia to increase your car’s speed!

These cylinder weights are made from a flexible steel composite, with the density of lead and a lower cost than zinc. The total weight of this set is 3 oz, distributed among two 3/8" x 5" cylinders. 

How to Add Cylinder Flex Weights to Your Pinewood Derby Car:

• Place your car block, axles, and wheels on a scale

• Cut the cylinders with scissors to just under 0.1 oz of your race’s maximum permitted weight

• Example: If your race’s maximum weight is 5 oz, you’ll cut these flex weights to bring the total weight of your car to 4.9 oz

• Drill two 7/16” holes in the rear of your car block

• The cylinders are 3/8", so a slightly larger drill bit creates room to slide them in

• Insert the weights and seal with wood filler
