I made an airdam from the coroplast I got at work today. I measured the lowest point on car which was lower a-arms @ 6" ground clearance. I made the airdam to sit at 5". Does this sound about right? I may also raise the middle of airdam into a slight taper up from outside edges, and build in tires "dams?" I also need to know how much should this help mileage, anyone?

I am new to modding for mileage I have done for speed power but not mileage, always the other way. I am addicted now. Only had car about 3 weeks and can't keep my hands off it, I just don't wanna do the wrong things. I have no instrumentation yet going to build the MPGuino one but saving pennies again for it.

Here is a couple pics of the airdam.
