Over all I am very happy with the wing. It looks great and is strong enough to hold up to the speed I take the car. It is sold at speed and does not bend or flex while driving. Shipping was very fast and the wing came very well packaged. There are a few issue though that can mostly be fixed easily.
1) They send a lot of hardware with the wing, but it doesn't do anything with this wing. Its mainly wood screws. They don't even send the nuts for the studs of the wing. You'll need to go down to a hardware store and get M6 x 1.00 nuts along with washer and lock washers before installation.
2) It awesome that the studs are not just carbon fibered in, but they use a metal sleave that is threaded. The issue is that the treading is very shallow, only three threads, and its easy to strip them out. I would get some two part epoxy to put on the threads to hold them in better.
3) This is the bad part and the reason I'm not giving the wing 5 stars. The center piece with the 3rd brake light does not fit. It is just a tad to wide for the opening of the wing. It can be forced into place but I don't like forcing things. Also I just does not fit with the boot/trunk. The boot/trunk lid of the GTR is curved and the bottom of the center piece is fully flat. This leaves gaps on both sides of the piece with the center making contact. This also forces the center piece to sit high and not line up with the rest of the wing. This leaves you with two options. 1) just run without it because its not really necessary anyway unless you are like me and like the look, or 2) run it anyway and deal with the issues stated above.
As a note I am communicating with CT Carbon and hope to work with them to fix this issue for future purchasers. If allowed I will update this review as we work to fix the issue and will post pics of the current set up if I can find a way.
