Similar to what euromodder said, the aero tests are very difficult because they are subject to so many variables. I would say the most reliable aero-mods are the grill block, side mirror delete, and pizza pan wheel covers. The belly pan is great but there is a risk that you will design it incorrectly and lower your MPG. Similarly in another thread, someone did do an MPG test of their wheel skirt and was getting *worse* MPG with the skirt installed.
Here are two albums for you to look at :
Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com - cfg83's Album: Car Styling
Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com - cfg83's Album: 1981 Peugeot Vera
