I think belly pans a great way to smooth out the bottom of the car. An air dam increases frontal area and drags the air underneath along with the the car. I agree they are a pain for maintenance, but I have had them on for 8 years. The rear half lasts longer than the part under the engine, if they are made from coroplast. They keep the snow from packing up under the car when you ram through a snow bank. The main problem I have when off roading are branches or corn stalks ripping off the front skirt bungee cords under the car or if the front wheel is in a rut and the tire gets under the skirt it gets ripped off. Putting the bungees inside the belly pan and trimming the skirt would fix this. A belly pan is one aeromod that is stealth.
