Somewhere in the forum is a full sized Dodge Ram pick-up truck with a huge front air dam.

He said it lowered his mpg, but that may have been because he went too low and increased his frontal area.

The reason I bring it up is the dam went above bumper height, and could be close to the look you can achieve sans bumper.

I just upgraded to a conveyor belt chin spoiler on my S10 pick-up truck, check out the links in my signature below.

Idea;
Flat metal arced where the top of the bumper should be, then drape down with material and have a few angled kickers to help keep form at speed?

Examples: for inspiration

Here is what I did to brace a thicker but more expensive conveyor belt material.

My truck as seen above is 7-inches clear, and I try not to pull up all the way to parking curbs.

It's high enough for a Michigan winter, even with record snowfall.

7-inches is good on my S-10 4x4, but perhaps because the previous owner raised it 1-1/2" (closer to 2-inches), a stock 4x4 S-10 could go to 5-6", and a 2WD about 4-inches.

Trick is to check under the truck for the lowest thing (rear differential and front A-arms) and make that the bottom lip of the chin spoiler height.
