he said that they are brembo oem rotors WITH a brembo stamp on them (many ebay guys sell bs rotors claiming they are brembo)... They have a black coating like in the pics that is resistant upto 1000f of heat, so no worries about rust! However, they are drilled at his shop, not by brembo (this is normal for most drilled or slotted rotors.) All in all the guy was honest and helpful, his feedback is really good.. If i wasnt debating big brakes i would have probably bought them :) hope that helps...
