These Stainless Steel Brakes Big Bite cross-drilled brake rotors are precision-drilled and mill-slotted to maintain better stopping power in rain, dissipate heat, and clean the brake pad surface. They are manufactured from a superior metal alloy composition to maximize durability, reduce heat-related stress, and eliminate warping, and they typically last 35 percent longer than OEM brake rotors. All rotors are protected through a zinc electroplating treatment to prevent rust.
