To make clear this was a Photoshop concept to help start & stimulate aero concepts for 240SX aero mods. In another thread there was a Z racing car that went through wind tunnel tests. They tested & got good numbers on some body modifications; semi-blocked front valance, side skirts & wheel arches. There are existing 240SX bodykits that could accomplish some of this for eco-modders. This PS study modified an existing kit & extended eco-modder ideas & concepts to create it.
