Google Ferrari 296 underbody, I can't copy the images for some reason but here are some sources:

This is very formula 1 esque, with how they're using floor fences to generate vortices to improve floor performance, and generate out wash to seal the floor.
But for the street car I suspect it's to push out the tire wake more than anything, so it doesn't impact floor performance - since the Ferrari does have a very flat floor benefits of being mid engine and not having exhaust pipes that need to be cooled, but you do lose a lot of diffuser volume as a result).
For our cars it'll be hard to replicate this without a proper 3d scan to run in cfd so we can see how he's to position these strakes to push out the tire wake. Also you don't want to put the strake in a region of dirty air flow because it won't be efficient, and you don't want to crank the angle of the strake too hard or else it'll flow separate and be less effective. Essentially it's not as simply as adding strakes and expecting huge benefits.
I think we'd get more benefits venting the wheel well and removing all that positive pressure, it'll decrease lift which is always a good thing.
