This listing is for a Legends Car brake rotor that has been machined from the minimum wear thickness to the maximum wear thickness to save weight (They are not completely turned to the maximum, we leave enough to true them up once or twice). These rotors weigh 6 pounds 6 ounces saving you approximately 2 pounds 6 ounces per rotor from the stock rotors for a total weight savings of approximately 4 pounds 12 ounces on the front of a car.
