This is mine, but not carbon fiber. I just installed it last week. I only used the 3 screws on the bottom, like the other guy mentioned, but I drilled into the muffler side of the bumper cover for one screw because I felt it was a little loose.
Fair warning, a lot of people have stated that the CF version does not look nearly as good on the car as expected. But obviously, that's their own personal opinion and I have not ever seen the CF version.
I also had to do a LOT of trimming around the exhaust port to make my Corsa exhaust tips fit properly.
