Them newest in sintered metal brake pad fusion technology. Has the highest friction rating possible 0.6 for strong, fade-free stopping power. Pad blend includes molybdenum metal and tungsten additives to enhance friction performance for the life of the pad. No lead, iron or steel additives; no more rotor outline etching or rotor stiction. Super-fast bed-in, full friction after 10 to 15 race stop uses. Great heat cycle ability; pads cool after the race and perform just as strong the next race day
