I'm reviving an older thread, but I wanted to point out something about this spoiler, very minor:
Because the third brake light is not installed quite at the same place and the washer fluid nozzle is on the brake light, it's really shitty how it sprays the rear window now. Being up north and using it in winter, it really shows. With the stock wing, it basically shoots in the middle of the window offset to the side a bit, but the Delta wing shoots more on top, so the washer almost just drips downs the window.
Not much an issue down south, but in winter it's useful for it to shoot properly.
I'll eventually find my pictures from when I installed it and post them.
