Not sure if this should be posted here or in the B5 forum, but does anyone know if the OEM wheels on the B5 S4 were made by Ronal as well as Avus? I have a set of S4 17" with the Audi stamp on them, but they're made by Ronal, not Avus. Possibly due to different production runs with supply contracts given to both German companies? Anyone with any insight on this?
