Here's mine:

It's the aerokit 2 wing. The lip beneath it is one of the wings that mounts in place of the retractable spoiler. Like others, I had problems with the retractable wing's mounting points cracking. I had a body shop mold that wing into a fiberglass trunk lid, and I got rid of all of the retractable mechanism. Between the glass trunk lid and the removal of the retractable stuff, I had a net loss of about 25 pounds...and I've got more downforce at the rear from the new setup. And I love the way it looks.
