sail panels with cut outs

Just curious what this actually does. I see a lot of LM with these and just a few mods. Is it more for aero or what?

The idea is that the car is sideways going up the straight so open sail allows more air on spoiler. If you have a car with a small or no spoiler, the advantage isn't there.

OK, thanks.
