Done properly it may help w/ aero. So if you track it may make sense. As for looks, my eyes says no. Your eyes may see roses. Have you seen the movie Shallow Hal?

Leave 'em for the EVOs

Vortex Generators ( VG's)
 

Reality is from an aerodynamic view point, yes they do work in many ways. However, only after about 75MPH do you get any gain. And for max gain, you need to have a rear diffuse panel installed as well. Air coming from the topside of the car swirls clockwise at the back of the car, air coming from underneath swirls counter clockwise in the same area. This creates disruptive turbulence. You want the air to pass over the car and under the car as smoothly and quickly as possible. This is what these two items do. In conjunction, down force is created. Which is always what you want for top speed and handling.

Four year old thread. Do you think anyone originally in it cares anymore?
