I've seen you ask this question in 3 separate threads. Honestly, I doubt anyone here knows, and if they did say something, it's probably something they 'heard' on the internet.
Your best option is to call a dealer or two and ask them. I'd bet they'd say IDK, or you get different answers between different dealers.
Is there a particular material you want? If so, I'd suggest buying any brand that says it's that material. Otherwise, the OEM pads work great, whatever it is they're made of, and they don't generally destroy your rotors.
