I have matt black alloys on mine but they have Audi hub cups, I have kept them on as they are black as I didnt want to put silver S on them. WHere did you get you black ones from and how much?
I fitted my caps today. Got them from Ebay in the end for £7.95 for 4. They are 75 mm self adhesive and fit flush over the gap. Really really happy with them far cheaper than the OEM versions as you wouldn't know the difference between these and the OEM ones
