Pinewood Derby FlexWeight

What is FlexWeight?

FlexWeight is a dense, flexible material with an aggressive adhesive strip (included). FlexWeight can be cut with scissors to the desired shape and then attached to a pinewood derby car. FlexWeight is 1/8 inch thick (slightly thinner than the zinc underbody weights sold at hobby shops). It is normally attached to the bottom of a pinewood derby car, but can be placed on the top or sides as desired.

FlexWeight is denser than zinc weights (a typical zinc underbody weight is only 2 ounces), so more weight can be placed near the back of the car.
