I also just took delivery of my 2017 911 S about one week ago, and like you, I have been researching paint codes to change my wheel color to platinum satin. However, I am now thinking I like the silver since they brighten up the car. This is coming from a guy who just got rid of my z51 C7 with black wheels. I did have full paint correction, window tinting, Xpel and Opticoat Pro done 2 days ago. I did the same exact protection on my C7 upon delivery and I am a believer. You have a beautiful car!
