What sets the DFC Geostop Coated Smooth Brake Rotor from the standard rotors is its patented Geostop® finish that offers superior corrosion protection. With this special coating, rotor life is extended, and it means it is processed dry, shipped dry, and ready to install without the need for additional preparation. Yes, no need to degrease this product, so it saves you a great deal of time and money during installation. Each DFC brake rotor goes through stringent machining and balancing processes to ensure it has the smoothest finish possible for improved initial break-in. Once all these processes are completed, it is then 100% inspected for exact fit, efficiency, and performance, so you can rest easy that it will match your vehicle’s braking requirements. It’s good for the environment too, as it is made to meet EPA regulations. Backed by a 12-month or 12,000-mile limited warranty, you sure can never go wrong with DFC’s Hi-Carbon Alloy Geostop Coated Smooth Brake Rotor.
