All Performance Friction compounds have similar relative density, structural integrity, compressibility and Rockwell hardness. In the range of medium to hard, Performance Friction pads are among the few that can offer excellent stopping power plus excellent wear characteristics of both the pad and disc. The difference in compounds is a measure of the characteristics of that compound, rather than a measure of its softness or hardness.
