Sorry for reviving a thread from the dead.
Just wanted to say that I have bought the carbon fibre mines style front splitter from Grams Styling. Hopefully I can save you before you buy it. I sent back my first one because it had so many imperfections, dents, scratches, broken corner and the carbon pattern distorted in the middle (hard to miss).
But the main thing was that it didn't fit the bumper especially around the curves on the sides it had massive gaps. Plus it didnt reach the grill it just stopped halfway and that part hadn't been cut straight so visually stuck out a mile. When I queried about that they said they all are like that and you just paint it black, even though the pictures I sent them clearly showed my 350z as being black and painting a gap doesn't fill it.
Anyway they said they had revised the splitter, but I didnt want it if it was anything like the first, they assured me it wouldn't be.
The second one is just as bad and after a sarcastic email from them after I said I just want to post it back for a refund. I then thought I would have problems getting my money back, so I am going up to them with the splitter to show them how bad it is. Just waiting for them to get back to me with their opening times as their website doesn't have a contact number.
I can't post pictures for some reason but they didn't really show how bad it was anyway.
