Speed tested?
My concern is the shape of the underside. that unfinished/concave underside will play havoc with the air passing under it and I don't think I'd trust it at high speeds. it really needs to be a smooth flat surface. Those downward rolled edges on the underside would generate lift and drag. Probably to the point at high speeds it would tear them right off of the self taping screws. That is all assumption though based off of the underside shape.
half the time 3/s cars are on jackstands...c'mon now...

A flat piece of ABS black plastic cut out the same shape would be better for the airflow.
Or even a flat sheet of metal, the important thing is "FLAT"
Not so sure it is as much of an issue as you are making it out to be.
A speed test will tell the tale. (GoPro vid)
It is also solved pretty easily by filling/sloping the leading, and trailing under-edge with filler, or spray foam. THe outside edge has no effect. Not something the end user should have to do granted, but can easily be done before shipment of the product.
Also understand that if this is glassed in to fill the void you just threw your jacking ability out the window.
You can leave a small section out for the jacking points or make a removable plug to still use them.
Mine were so bad from the previous owners, both side welds are all bent to shit all the way down the sides I had to pry a lot of it back as straight as I could to get the side skirts on. I use the front jack point under the bumper with my low-pro jack and the trailer hitch to raise the rear. One it is high enough on the 1st or 2nd notch of the jack stand the I use different points on the rear and front sub-frame.
I've been to 150mph several times with mine on my FD which are only held on by 4 screws using existing screw holes since i wouldnt allow adding holes to my car and 3M 2 sided tape. They are still there.

Oh and yes of course these are just cosmetics. No on here is fast enough of a driver for them to be a functional aero part.
