One of the gems we uncovered in Orlando was this carbon-ceramic rotor technology from Turbine Rotors (www.turbinebrakerotors.com). These rotors for '05-'12 Mustangs weigh in at 9 pounds each. They are also said to offer better cooling, longer wear, and even better fuel economy. For a more affordable option, Turbine Rotors also has a stainless steel variant using the same technology. For those up north, both feature rust-free components.
