Recently, I received some brakes from a friend (Cobra R). The interesting thing I noticed was the scrub pattern on the rotors. Only a pattern of less than 2 inches was shown. On my PBR setup it is about 2 1/4 inches. He mentioned that the pads were "hawks". I don't know if they are designed to utilize the smaller area on the rotor or not. The difference in diameter of the rotors is PBR=11 and Cobra R=13. If anyone has experienced this situation, it would be appreciated if you could clarify. Usually more is better with pad to rotor contact area. It will be a while before I change out the systems. Is there a pad that would be optimal for the Cobra Rs? I also saw an image of brake cooling tubes on a Cobra R but don' t know if it was stock or add on. I've been waiting for an excuse to install the system to utilize the openings in the nose for a while (the adaptors that connect from the nose to use a 3 inch flex tube to the backing plate on the brakes).
