your still supporting the oem manufacture though, they are the ones who made the car that you bought, they got money from the purchase. as far as aftermarket oem style bumper covers, im sure those companies have to pay money to the oem manufactures in order to reproduce them or i would guess there would be some serious copyright infringment going on. when you buy a fake/copy wheel, the original wheel company isn’t getting anything out of it except knowing that you really like there wheels, but are too cheap to buy them and would rather just pretty much kick them in the nuts. because replica wheels can do somehting as simple as put the lug holes in a different spot and they are still gonna fit on any car and look the same but not have to worry about copyrights.
