Hello Eugenio,
without an approval for the wheels you will not get the car running in Germany. I didn't find any wheel manufacturer in the US who had the approval. Finally I found a German manufacturer "Schmidt Revolution" who produce wheels 18 inch and my size I requested. the German TUV only requested the design should have been available in the 1970 years in order to get the historic number plate. I like the design, but these do not look like Campagnola.
hope we meet this year in Düsseldorf area, reg. Uli
happy new year
