On a Ferrari,where there is a dedicated radiator extractor vent designed into the belly pan,no such air would be blasting out the wheel-wells,and nothing fancy would be required to enhance the flow there.
Remember though,these supercars,while very 'cool' have pickup truck-like drag coefficients,and are designed for high-speed stability more than any other parameter.They're not really a model of efficiency.

So the trailing radii are useless if you don't have air flowing through the wheel wells? Am I reading this correctly?
And I suppose cars that do have the trailing radii or other vents in the wheel well but also dedicated radiator extractor vents, it is there to handle whatever other flow that does make it to the wheel well?
