Mine didn't fit right also. Looked like there's too much carbon behind the screw housing and it ws hitting the aluminum housing of the bumper and prevented the CF surround from lining up properly. Five minutes with the dremel fixed that. But even with the fix, the CF surround's side still stick out very slightly from the bumper, not very noticeable, but still not 100% flush. The carbon fiber weave is oriented at a slight angle also. But overall, I like the look of the piece on the car, just wish it would fit better and had perfect weave alignment. I'd love to get a diffuser and front splitter when they become available, but definitely would want to make sure the quality and fit is better before I put my order in.
