Looking at the specs of the QFM pads, they seem to be pretty reasonable specs, the co-efficiency seems a little higher than others but I wonder what compound is it made of? Are they semi-metallic? Carbon? Non-Asbestos? :) I've got Endless MX72 on the front, they're brilliant :) If you look at their specs, its 50 - 700deg temp range, Average Coefficient of Friction 0.37 - 0.47, better than most regarding brake dust, brake fade, Controlability and pedal feel. This is compared to the major JDM brands like Project Mu, WinMax and ACRE. I've also tried Brembo and Bendix. Endless kills most them in almost every department (when comparing relevant series)
