There has been a visible difference between the OEM pads and the aftermarket ones I have brought. The OEM have a thin perforated metal backing plate. I'm assuming it's for thermal insulating?
My advice is don't throw your old OEM pads away if going to aftermarket cause that backing plate easily lifts off and can be clipped over the aftermarket ones.
