Raybestos R-Line rotors are engineered for everyday driving conditions. Offering an industry-leading, 99.8% coverage for import and domestic cars, light trucks and SUVs, our PG rotors provide the highest level of dependability, safety, and performance.Our R-Line rotors are developed from OE samples and made with G3000-qualified material, ensuring form, fit and function for a dependable performance. They meet the SAE standard for tensile strength, providing structural integrity and maximum service life, and have a non-directional ground finish for a product that is ready to install right out of the box.Our R-Line rotors come with a lateral runout of 0.004 in. or less and a thickness variation of less than 0.0005 in., ensuring less pedal pulsation, less brake noise, and extended pad life. They are 100% validated and mill balanced as needed. This helps minimize the thickness variation of the rotor, guaranteeing proper balance, minimized vibration, and quieter, smoother stopping.
