Use the PineCar® weight to boost the speed of your derby racer by increasing its overall weight. This essential PineCar accessory plays an important role in derby races, even on the race day. It can be installed by drilling a 0.375-inch hole into your vehicles and inserting the weight in it. Make a round weight out of this combo weight by putting flat sides of two weights together. In addition, this Derby weight can be attached to the sides of your car according to weight requirement.
