Cooling fins for the oil cooler behind it?? Total wild guess.

i didnt take a look for myself, but if those are vents, i would guess they are for air flow to the brakes. if they are just ridges with no openings, then i have no idea.

If no openings then most likely cooling fins. Increase surface area for better heat dissipation.

maybe to decrease water splashing if there aren't any opening.

They are there so you can scratch your back when doing your brakes.

This and that.
It lets air through and that gives better aerodynamics to the car and cools the brakes at the same time. That would be my guess.

yep, the bumper lets air in, hits the oil cooler behind than the air leaves through those vents.

There is a small radiator and fan on the other side of this.

On a side note, go ahead and clean that area up while you have the wheel off. Makes the car look new!
