Hi Awillard..,
Did not go to UIUC and major in aeronautics, did you? With a moniker like that, seems you might have spent some time at Willard Airport.
Anyway. Yes, the Prius, and other aero cars typically have a stock diverter in front of the wheel well opening. Its just a piece of plastic that is thick enough not to deflect in the wind, and extends downward and slanted so that the inboard edge is slightly (3/4 of an inch) forward. This would help on your vehicle too. In some pictures on one of these sites, the professional aerodynamicists had taken mud flaps and mounted them on the front edge of the wheel well as a mockup during valuable wind-tunnel time.
