I just got my R8 back today, and had the grill outside ring and quattro badge done in black too. I had Rich at OEMPlus take care of it for me, when they removed the front plate grill and put on the plate delete grill (the one in original post).
Back when I had the stock grill I took a little black paint to that nasty **** Quatro. Possibly the first mod I made. Since then I switched to a PPI carbon grill that I am VERY pleased with. JUST PURE CARBON , and saved a few pounds at same time getting rid of all the nasty. I. M. O.
