3 oz Flat Flex Weights | Stick-On Derby Car Weights

Pinewood Derby stick-on weights leverage inertia to increase your car’s speed straight to the podium!

This flat flex weight is made from a flexible steel composite, with the density of lead and a lower cost than zinc. It’s designed with self-adhesive backing and can be cut with scissors for easy application. The total weight of this panel is 3 oz and measures 5" x 1-1/2" X 1/8".

How to Attach Stick-On Weights to a Pinewood Derby Car:

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

• Cut the flex weight 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 mass of your car to 4.9 oz

• Remove the self-adhesive backing and apply anywhere to your car
