Manufactured for European and heavy vehicles, our High Carbon iron formulations (Molybdenum, Chromium, and Carbon) enhances noise dampening characteristics, while providing high strength, and increased thermal conductivity compared to standard discs, which increases durability. Engineered with High Carbon castings to enhance noise dampening characteristics, while providing strength, stability, durability, and performance. GEOMET Finish throughout the entire rotor which promises to deliver superior corrosion protection. The GEOMET coating is processed dry, shipped dry, and ready to install without any additional preparation. Drilled and slotted rotors will grab more bite to the brake pads giving you shorter stopping distance especially in wet weather. The drilled holes will reduce the heat that builds on the rotor. The slots on the rotor removes brake and road debris and prevent pad glazing. An average brake job takes 1.25-2.5 hours per axle. Without the need to clean an oil covered rotor, this saves a tremendous amount of time and money during the installation process. Coupled with our application-specific DFC brake pads, these rotors provide the best possible braking right out of the box compared to anything else in the market!.
