The Porsche stem covering caps are a good choice to blend into the anodized lips of the Fuchs. I wanted a stem that doesn't deflect when using air line/gauge so I went with Ferrari stems per Weidman's (wheel refinisher) recommendations. They are aluminum and blend in nice. Wheels are refinished with painted centers and anodized lips. This is the 16x7 on the rear. The 16x6 on the front has a tighter fit for the base of the stem, but Weidman made it work.
