The new floor pan immediately catches the eye, as it now features two side fins which are visibly more developed compared to the previous version. The idea, which combines aesthetics and optimization of air flow, is to cover the entire area enclosed between the chassis tubes in the pedal area. An idea that other manufacturers are experimenting more or less with. For the World Championship in Lonato, Birel ART has opted for the 506-front bumper spoiler manufactured by KG. The Lissone company offers customers the choice between the new version and the Free Line FL F1 model (the accessories line by Birel ART). The choice between the two is dictated by aerodynamic needs, different for each circuit, and the right compromise between channeling the air flow and aerodynamic load on the front wheels.
