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 OE brake 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.
