Okay, we all know that Subaru added the little winglet on the STI as a response to the Evo MR's vortex generator. Except Subaru couldn't make an EXACT copy, so they just made it a flat wing blade. Well, Zero Sports has come up with what Subaru probably WANTED to do in the first place. This is a replacement blade for the OEM winglet that has vortex generator triangles molded into it, top and bottom. It's a direct replacement for your stock winglet blade.
If you somehow avoided learning about vortex generators, the idea is to create turbulent spinning air (vortices) that helps air to act more effectively the main rear wing.
Note that this is for 2006-07 WRX STI only. It will not fit any other car. It's the wing blade only, and does not come with the side supports, which are standard on the 2006+ STI.
Made of fiber-reinforced plastic. Unpainted, black in color. (You will want to have this piece painted; it is not finished.)
