98x5,98x4 is Fiat, know of no cars of that pattern bar A-R. It might turn out to be cheaper to make adapters to VW Audi 5 stud. You did not mention inset/offset, try googling Revolution wheels or Minilite(tech-del) but I suspect the exchange rate will kill EU prices.Also try Silverlake.co.uk,brilliant scrap yard.
