What makes DFC Brake Rotors’ GeoStop® coating special? When this coating is applied in each DFC rotor, it means it is processed dry, shipped dry, and ready to install. That’s right! No need to clean the rotor once you take it out of the box, so this saves you a lot of time and money. How about performance? DFC knows all too well that performance must never be compromised by looks. So, each rotor casting is processed in DFC’s state-of-the-art manufacturing facilities—from CNC machining and mill balancing to testing and evaluation—for quieter, smoother stops and zero vibration at any speed. And since it is made with premium G3000/G11H18 cast iron, it stays strong and durable when braking in any condition. All DFC Geostop Coated Brake Rotors come with a 12,000-mile or 12-month limited warranty against defects in material and craftsmanship.
