I put a Type-R wing on my previously wingless Integra and it makes a difference on the highway. The back end feels a little lower and the car feels like it hugs the road more. But, it's not a huge difference, and it's certainly not something that the car had a need for. I've had it up to 130, both with and without the wing, and it rode really nice and smooth both times. I can't honestly say that I remember any difference. At highway speeds that I drive every day, such as 80, I noticed the difference at first, but I quickly got used to it.

I bought it because I liked how it looked. Sure, it has a mild performance benefit, but I'm not going to BS you and try to say I bought it for performance like the riceboys with the giant obnoxious wings will. I figured that a wing designed by Honda for the Integra's high performance model wouldn't have undesirable results, and I was right. Different wings and different cars may be another story. I know a guy that put a Supra wing on a Cavalier. We call it a shopping cart because the wing is about as high as the roof of the car. And go figure, he's convinced that wings don't make any performance improvement at all, because his doesn't.

Who knows, maybe my wing is helping holding the back end down around turns as well. I have no proof one way or another, so I'm not going to try to say that it does or doesn't. In any case, it's there because I like how it looks. It's hardly an essential performance mod.

I know there's plenty of crackpots that are either strongly for or against it, but I've yet to come across one of them that has any actual understanding of physics at all. Besides, who cares... it's your car, don't let other people tell you what to do with it.
