Thanks for the compiment. I was just with 40 Crossfires last weekend at Texas Motor Speedway and most everyone seemed to like the wheels and many said they looked better in person. I was at the MB dealer today picking up the last bunch of parts that I think I will need for the V8 conversion. One of the parts guys helped carry parts to my car. He loved the center caps and said he had never seen that type of AMG center cap. I told him they were the really rare and expensive ones I was surprised that the inside of the caps said Brabus! Why would Brabus make AMG center caps? The SL550 wheels are 18's like my last ones but they look larger. I have had people think I went 19's all the way around. They also have more of a dished look in person.
