When I was looking for an SVT, I was specifically looking for one w/o the factory wing because I really only like them on the SE's and I planned to put a custom spoiler on. I did notice a little difference in the pickup but that was it. The spoiler is really heavy and now my trunk doesn't open right. Since it is so heavy, when you press the button or pull on the latch you have to lift up at the same time. Kinda sucks but oh well. I really like it and again you all just need to see it in person.
