Hawk Blue compound is a unique, high-tech friction material developed and manufactured by Hawk Brake for the racing community. All Ferro-CarbonTM materials exhibit non-fade performance and have been evaluated up to and beyond 1,800 degrees F. Each material offers lower wear rates and higher torque values than all other competition materials available on the market today. These pads are strictly for track use ONLY! Unlike the TMS carbon pads above, Hawks are not designed to perform at low temperatures that are normally experienced in ANY street car!
