Hello together, am new here and have a question: I drive an Omega B Caravan (Facelift) from Jan 2003 and have an acquaintance who drives a Vectra C Caravan OPC. He has already upgraded to 20 inches and offered me the 19 inch OPC rims with the Y Designe (at a fair price) Opel has of course no approvals for this and wants to know about it. What does a single acceptance or registration of a single report cost. Will the rims be registered at all? ? The OPC rims are 8*19 and have 235/35/19 rubbers on them. Would be very grateful about answers. Best regards The DTIler….
