Yes, I don't think the downwards projection needs to be as great as I show with the BMW, but my measurements (and the literature) shows this can create good downforce (and all else equal, that means less drag). At least some downwards curve... and I'd make it a gentle contour. |

Tires with higher pressure are narrower, reducing CDA?

Undercar airflow, pressures and lift - understanding how air dams, rough undersides and belly-pans influence lift.
(And decreasing lift normally decreases drag)
