I'm having a hell of a time finding steel wheels for our 2002 T4 weekender here in the states. No one sells them anymore over here as 2003 was the last of our transporters. I wanted to stick with a 16" rim, but the Mercedes Metris steelies at 17" and et50 are fairly reasonable at $70/wheel. Any reason not to use these guys? Would a VW center cap fit on the wheel so I could use that instead of the Merc one? Thanks!
