Low Profile Pinewood Derby BlockThis low profile wood block is only ¼″ thick. This thin body creates an extremely aerodynamic car and it allows you to place the majority of the car's weight exactly where you need it in order to optimize the placement of the center of gravity. This means more speed. This block is precision cut with a CNC guided laser for accuracy, balance and symmetry. These blocks meet all BSA Pinewood Derby dimensional requirements. The dimensions are 7″ long x 1¾″ wide x ¼″ thick.If you need axle holes or slots check out the Incinerator Body.
