BMW needs to have the molding very slightly changed to have the ends taper slightly down. That would ensure the ends don't lift and there's no danger of the middle section separating as that part has a very strong bond. I realize CF is more difficult to get perfect but this is one of the worst OEM fitments I've ever seen on any car which is inexcusable for the money they charge for the piece.

Mine fits fine. But of course it was port installed.

Mine fits perfect and the edges I bonded down. It is not the CF spoiler that is the problem. The problem is the stamping variation of the trunk lid. There is a dip at the edge and I have noticed that some have more of a dip than others.
