From what I have been able to find from searching, it seems that they are painted, but I'm not sure on the 2011. The previous owner had painted the calipers and I want them back red. I was able to flake a small piece of the dark paint off, but before I do anything too harsh, I need to know what they are. If they are powdercoated, I thought about using a little brake fluid on a rag and just take my time, but if they are painted, I don't really know what to use because I don't want to damage the original red. All help is greatly appreciated!
