Hawk Performance brings you these performance-designed direct OE replacement rotors, dubbed Hawk Performance quiet slot rotors. These quiet slot rotors combine the look, feel, and durability of true performance rotors with the fitment and convenience of an OE design. They feature unidirectional vanes, which eliminate the need for left and right side rotors. An optimal rotor vane and wall thickness improves their structural strength, noise dampening, and heat capacity. Their OE-style vane design, combined with an increased heat capacity, dramatically improves brake pad and rotor life. All Hawk Performance quiet slot rotors are finished with a GEOMET coating that protects both the internal and external surfaces from rust and corrosion. Their unique slot design increases initial bite, improves wet-weather braking performance, effectively removes gas and wear debris, and features visual wear indicators. When the slots are worn down and no longer visible, the quiet slot rotors should be replaced.
