Hikaru9 said:Those are called vortex generators, primarily used in aircrafts. In a technical stand point in aerodynamics they do serve a purpose, so to answer your question, they "do something". *^_^*
Maybe on an aircraft they do, but on an EVO? cmon, thats rice gear. I dont see them on STI's, GTI's or MS3's, let alone, anything else out there
