right got the 19s on my car and when i bought it at the dealer i noticed one had a very tiny bit of kerb damage and so they got the wheel sorted no problem. Couple of days back I clipped something which has caused a similar amount of damage. My local dealer seems to think these are diamond cut wheels and will have to be sent to a specilist wheel shop. Are they diamond cut though .. no mention of it when I asked for the original fix from the selling dealer. if anyone can shine any light on this i would be much obliged.
