regarding the center caps with the RC's the centre cap is made up of the centre dish, nut and cap.
The nut and dishes can be refurbed, however the VW/BBS logo will need to be replaced. The logo is basically a plastic cap with a embrossed logo stuck on. You can either buy a new 80mm cap, or opt for a new sticker. With the latter you would jusy need to peel off the old logo from the plastic cap and put the new one on top
Getting a new "VW" 80mm cap can be hard as from experience they only come with the whole centre cap assembly with nut and dish - so many buy used ones in better condition. BBS ones can be sourced on ebay/online etc with more ease.
Hope this helps
