KG present the new MK 20 bodywork kit , pairing with the HULK rear bumper/spoiler system. The goal for the MK 20 design project has been to address the aerodynamic of the bodywork as related to the chassis, taking into account and optimizing the frontal area and the air impact and the resistance to motion advancement. We created with the MK 20 a covering and curving front with no flat surfaces. CFD research allowed us to improve the total resistance to advancing motion of 6.7%, with a concurrent increase of downforce of 18%.
