Mike, over the weekend I looked at the box in which the Ate Power Discs came. It is marked, in German/English, for: Quattro 100 100 Quattro 200 200 Quattro part numbers: 447-615-301 A 447-615-301 B If I am not mistaken the US 5000 model, with or without turbo, is equivalent to one of the above. Regards, Martin.
