Bottom Weights for Your Pinewood Derby Car
This 1 oz. steel weight is designed to be attached to the bottom of your car. The thickness is less than 1/16" so it will not interfere with the 3/8" minimum clearance specified by most rules.
Use epoxy or other strong glue to attach the weight to the bottom of your car.
Two weights can be attached to the bottom of constant width cars.
They can also be used on the side of the car.
