Racecar engineers know the value of slotted brake rotors; they are lighter, have better cooling properties, and keep the brake pads cleaner for a better "bite". Now you can have the same advantage on your Mercedes, achieving a vast improvement over systems. We start with OE design Mercedes Rotors, precision machine them for the best possible performance, and then cadmium plate them to prevent rusting. Test show a significant drop in temperature under extreme use, and drivers report better "bite" on the cleaner pad surface.
