Stand out with a TWIN ARM SLIDER 240 w/slots: This body has a sleek aerodynamic profile to increase speed. By design most of the wood is removed from the center of the car, which enables you to put more weight in the rear, this feature dramatically increases the potential energy of your pinewood derby car. Each car comes equipped with holes drilled for perfect rear weight placement and balance using our lead wire or tungsten cylinders and the original kit axle slots are retained. Perfect for those races where the stock slots and wheelbase are required. Wheels and axles are sold separately to give your car that winning edge!
