The fitment on the face lift e53 grilles I ran was fine around the edges, but I did use silicon in key places as an extra to hold them in. The grille slats were cheap though. They were the 6 series style grille though as that was the only gloss offering at the time when I purchased them. Now I believe they have OEM e53 style available in both gloss and matte.

Right now I am rocking plasti-dipped OEM grilles with glossifier. They look good, but I'd prefer gloss OEM style grilles. Keep us updated as I might purchase another after market set if they are worth it.
