They are only exclusive to the ZL1 if GM denies people from ordering them through the parts department.
So to me the exclusivity of them is not what you are paying more for. When the black wheels first came out on the 2012 ZL1 they were also exclusive to only the ZL1 for that production year. I think GM is banking on the assumption that more people would choose to upgrade to the bright aluminum for the looks so they could make more money by selling those as the "up charge" option on the car.
