I don't care if it belong to a boxster or not, I got a speedbike, and a lot of friend with speedbike had gone crazy with chrome, but for it to stay nice, specially on wheel, is hell! I got problem keepking my stock wheel clean, so imagine on chrome..
Chrome is nice for show room, on road it's not practical, Go chrome only if you can handle to clean it twice a day, dirthy chrome is worst that non-chrome
