I installed the black diffusers on my 12 Grandsport, I used a 0000 steel wool pad to scuff the gloss finish, now with armor all on them they are a perfect match for the plastic lower valence. I used the template provided, but first I drilled 4 small holes in each diffuser,after sticking them to valence ( clean off armor all with provided cloth) I drilled through valence and attached with black headed machine screws, yes you can get your hand up in the cavity to put on a washer and nylock nut . very custom, and I am very fussy, great look.

Nice quality. To blend in better, I trimmed them down by 3/4 " keeping the same curve. I also ordered black and used fine steel wool to dull the finish to blend in with the rear facia. Would link to see the blades a little thicker.
