I need a trained eye please: I brought a set of used genuine 18" RS4 Alloys, one turned out to be buckled so I sourced another from ebay. I assumed all genuine RS4 18" woud be the same. It arrived today and it doesn't match. (ignore the aparent size difference, car is on 225/40/18, new wheel is on 235/40/18. Alloys themselves match in diameter and width). The space between the sets of spokes is bigger. The finish is duller than the ones already on the car. Is one kind a replica? If so which kind? Shiz of ebay is 9 times out of 10 a massive let down!!! Ones I brought last week installed, ebay one next to it: Last weeks purchace: Ebay purchace: Ebay purchace has part numbers stamped around the hub: Last weeks purchase has the numbers stamped on the rear of the spokes (no photo) Can anyone shed some light please?
