I ordered mine without the spoiler because I don't like the factory wing. It just sticks out awkwardly off the sides of the back. A lip type spoiler would have been a lot better integrated into the design. I, like most comment on this board, would of liked the car to have an M3-type lip spoiler. The Z on the other hand looks like it could use a flat wing around its big round but, but gets only a lip instead.

After seeing real pics(not the studio made advertising ones) of several of the aftermarket wings from people who bought and installed them, I arranged a group deal and got a Gialla rear lip. The Data Systems looks strange in person the way it travels up the sides of the trunk. The Impul looks great in the advertising photos, but on a real car the side lips that go over the tail lights look strange from any side angle. They only come halfway down the tail lights, so they look very tacked on from side angles. I saw pics of a car with the Gialla and it looked really good on that car, so I ordered one. I am extremely happy with it. It is extremely subtle, so a lot of people don't notice it when first glancing at the car. Looking at it from the back, it has a subtle curve that perfectly matches the curve of the tail lights. From the side, it extends a little off the tail and has a nice kick to it. It isn't a spoiler that was designed to be looked at 6" behind the car. If you look at if from 10' away in all directions, it is very apparent how well it blends into all of the car's lines. Installation was extremely easy(only 2 holes to drill). Last, it is functional. The back end is a lot tighter at 130+. If I didn't go Gialla, I would have remained wingless. On the other hand, I love the new front lip spoiler, so I couldn't wait to get one.
