I received the spoiler took it out of the box cleaned the area on the spoiler where I put the double sided tape on, cleaned the trunk area where the spoiler was going to be placed. I used alcohol swipes. I put it on without
taking off the tape as a test run to see how it fits and where to position the spoiler. I took the tape off stuck it on and it's been there ever since. The fit and color are dead on! It looks great
and it's on there until I decide to take it off. Best bang for the buck I have installed on my 2011 BMW 528i.
Beyond impressed with the quality of construction of this deck lid. Not only does it perfectly fit, the quality of paint is truly impressive. Blown away by how awesome this deck lid looks on my 535i xdrive.
Thanks guys!
