A couple years ago I installed a plastic panel as an air defector under my 08 GT. It did give me maybe .1mpg better, and the hood fluttered less, but it was less than ideal. Attaching it with zip ties to the K-member looked pretty amateur. My sister-in-law's fiance has a lift that he offered if I wanted to change the oil. That was easy and quick enough.
When I was done, I asked his opinion about installing some 24" wide aluminum flashing running from the radiator support to the lower chassis brace. I said I'd like to run it further aft, but I didn't see any way to support it. I also thought that I'd interfere with the cats, and he more or less agreed. Then he said, wait a minute, let me see.
He came back with a flat aluminum panel. It had been a sheet from which Chevy was going to make 67 Camaro test fender skirts. Anyway, it was thicker than flashing, and it was wider too.
It took a lot of trimming and punching and hammering, but it connects to the radiator support with fender bolts and nuts. At the rear, the simplest thing was to attach it with the chassis brace bolts and nuts.
The final product looks nice and reasonably professional. [There's an extra hole at the front b/c we were a little brain dead yesterday. Doesn't matter b/c the oem air deflector covers that area.] It took a couple hours on Fri and almost three this morning.
If you can't find an aluminum sheet, flashing is not a bad idea. You can get a roll of 24" wide flashing for about $2.50 a linear foot at home improvement stores. HD keeps it by the roofing materials.
