Well, theoretically, lowering the car will reduce frontal area and improve the fineness ratio of the vehicle. The resulting effect on fuel economy will depend on the vehicle and its design. An SUV/Pickup will benefit more whereas smaller, more streamlined cars will net lower gains.

A good set of progressive springs coupled with a good set of shocks can also minimize the decrease in ride quality.
