I'm with everyone else on this one, forget about the Erector Set wing. They look ridiculous, they make cops and theiving wanksta's look at your car twice, and they don't do a damn thing for your car, performance wise. I know, people say that "It creates downforce", well, our cars are fwd, we don't need extra downforce on the rear wheels, and how much hard cornering will you be doing at highway speeds and above? Because that's the only situation where that wing will have any effect.
If you want a bigger wing, go with the Type R wing, but OEM looks best to me.
