I have stock 17" S wheels that came on the Boxster that I use for Winter tires. So, when they went on it was time to repair and paint the SSR 18" wheels I use for Summer. Both the wife and I had curb rashed the front wheels so it was really a no brainer. They are for intents and purposes 2 piece wheels. The hubs are 2 part, but welded together. All I did was unbolt everything, sand it up and prime it. Here's what they looked like brand new and unmolested!
