I have not been experimenting with aerodynamics, but think that a full belly pan can do more than lowering and/or a front dam. If the intention of a front dam is to improve fuel economy you don't want to get a low pressure under the car, since that will cause turbulence. I THINK the best is modifications that gives a minimum stir-up of the air below the car, and that is HIGH ride height, a smooth belly and a front splitter.

The single most beneficial aero-mod seems to be a boat tail extension, but that's probably the most extreme mod you can think of. I would definitely look into at least a part kamm-back or boat tail extension, a front splitter and a flat belly before I go bezerk with all those tiny things such as wheel covers, removing windshielt wipers, grill block etc.
