No, sorry it's not.
For a start, my car is a 4-door, and the wing I wanted was raised above the boor, mounted on 2 supports.
Nothing huge or attention-catching, just a nice understated boot-lid spoiler in the same colour as the car (gun-metal grey in my case) with a long thin brake light set into it.
PS: If anyone can tell me how to succesfully add an attachment, I'd be grateful.
