The Derby Monkey Inferno EX Pinewood Derby Car Body is engineered with only one thing in mind... sheer speed. The body design, weight pockets, center of mass, and aerodynamics are all optimized for top performance. The body is laser cut with a CNC guided laser. This creates a body with perfect balance and symmetry. The body meets all BSA Pinewood Derby dimensional requirements. The Inferno EX Body Features:Raised Left Front Pinewood Derby LegalTungsten Cubes are the recommended weights. Building super-low profile bodies is a trademark of the Derby Monkey Garage. All of the derby cars we build for competition are only ¼? thick. This thin body creates an extremely aerodynamic car and it allows us to place the majority of the car's weight exactly where we need it in order to optimize the placement of the center of gravity. This means more speed. Our cars consistently finish in first place at our district derbies.
