Called the dealership today on a new spoiler, they said they had 2 different kinds? One is w/ the aero package, and the other was just stock spoiler. Does anyone know the difference for a 03 coupe? (they could not answer the above question)

 

If you have a sedan, then i dont know what they are talking about since there is only one as far as i know. If you have a coupe, the spoiler from 03-05 is different from the 06 spoiler. Maybe thats what they meant by having two kinds

 

Aero package comes w/ the underbody diffusers along w/ the trunk spoiler.
