First impression is that it won't work as envisioned. Sorry.

I say that because they don't do anything to address the drop-off angle of the back glass that causes the turbulence in the first place, like a proper spoiler might.

If there is flow through them it appears to me there would be significant surface drag- lots of surface area there.

I just don't see the mechanism at work here to reduce turbulence except maybe on the outermost pair, and even then...

Rear visibility... sort of. Through the rear view mirror straight back- yes. All else- no.
