Small ones like those are just for looks, I could be wrong but it's my understanding the primary purpose of the 2 to 3 inch versions (like NASCAR) is to add stability like a rear vertical stabilzer on an airplane or a vertical fin on a fish. I think they also adds a help clean up some of the turbulent airflow as well.

seems odd to put something just for looks on a car that already has abysmal viewing as it is. But agree also can't believe that they actually do anything aerodynamically, most spoilers on cars are for looks.
