My Factory are tarnished and faded from possibly a wheel cleaner. Mechanically they are fine. To have them off the car for a week to be powdercoated is a logistical challenge and I hear they need to be rebuilt after. My first though was get a second set, however that still leaves me with dull factory finish that will fade over time, my second thought it pick up a pair of OEM 07-12 GT500s which are powdercoated black from factory and look much cleaner and then possibly sell my stock units. If I'm not mistaken these are identical to mine and would bolt right up to a 14 inch rotor. Might pick up ss lines while I'm at it. Let me know if those are the same..
