Chin Spoiler - fast/easy/cheap/effective
Extra deep garden edging 6" deep x 20 foot long coil purchased at ACE Hardware for approx. $12.00.
Secured straight up though the lip with a dozen Stainless Steel #8 Phillips screws 32 tread count, 1 inch long, lock nuts (nylon insert type) 9mm.
I'll post the fuel savings later in the week. For the first 50 miles driven today I've gone though less than 1/8 of a tank, normal is a hair over 1/8 tank. At 70 mph the engine is turning at 2,050 rpm, I think that is about 200 rpm less than before. So it's like I'm driving 5 mph slower than actual speed on the highway, and that is bound to add up. Only a couple of hours to install.

I have enough material left over for two more trucks.
Automotive plus fill the binding holes, first securing point is centered.
Curb clearance is reduced from about 13 inches down to 7 or 8 inches, still double of my old Porsche 911 which has more of an overhang. I'm used to not pulling all the way up to a curb, don't do this modification if you are a curb knocker, or at least use a standard 4 inch PVC lawn edging in lieu of the deeper 6 inch one shown.
Some air gets in through the tow hooks, I'm not going to block these off until I can test engine temp's in summer while towing.
Compare it to my neighbor's stock S-10 4x4, from mid bumper down all that air gets compressed then sucked up under the vehicle by the vacuum/neg air pressure under the floor and tumbles around in drag causing vortexes.
