I think the best thing, regarding drag, would be to keep the air under the car from blowing out through the wheel openings. Those spinning wheels impart a LOT of kinetic energy to air, all at the expense of fuel economy. In fact, I'd like to figure out how to add fairing on the inboard side of the wheels (particularly the fronts) to keep the underside air from positively being able to migrate out past the wheels/tires. Perhaps a coroplast assembly mounted on the strut and knuckle to let it steer/bounce with the wheel.
