I have just recently purchased a set of 4 17" original Audi RS4 style wheels for my A3. I'm over the moon with them (I know most of you would have gone for 18's or bigger!), however one of the metal rings from inside the centre caps is missing. I went to the stealers to buy one but surprise, surprise they said I had to buy the hole cap @ £21.33 (thats over £85 a set!!!!!) I have two questions - does any one know where I can buy the metal ring? if not, is there anything else I can use instead? Cheers Bob - I just cant bring myself to give the stealers £21 for a metal ring!!
