This 3D printed bumper fits the BD12/11 series of competition touring cars and features a 3D-designed honeycomb structure for lightweight construction and minimal weight. The flexi- ble material is made to be moderately strong and easily resists body deformation due to aero- dynamic drag.
It has significant functional advantages over standard urethane bumpers. Air flowing into the underside of the chassis during driving is drawn into the body from the underside of the bumper, thereby reducing chassis lift and enhancing the sense of ground contact. This tends to improve steering traceability and stability in high-speed corners.
