I was hoping to do something to improve the air flow. I know that if I lowered the car I could reduce some of the air flow and improve my cd/reduce drag. I would be guessing as to whether the "V" would be better. My thought was to add 1-2" of rubber or plastic to the chin of the bumper which would simulate lowering the car with a $400 suspension kit. The frontal area would increase slightly but the dirty underside would gain from the reduced air flow. Side skirts at 1-2" would be planned also. I don't have the time or tools required to do a belly pan which sounds like it would be best.
