The R1 Concepts eLine drilled and slotted brake rotor is a direct-fit replacement built to improve heat dissipation and braking consistency. Cross-drilled holes vent heat and gas away from the rotor face while the curved slots sweep water, dust, and pad glaze off the pad surface for a firmer, more repeatable bite. The casting carries a protective silver zinc coating that resists rust on the non-contact surfaces, and each rotor is mill-balanced to OE specification for smooth, vibration-free braking.
