The R1 Concepts drilled black front-right brake rotor for 2010–2022 Toyota 4Runner is a fitment-specific drilled rotor intended for the front-right position to aid pad ventilation and water evacuation. Designed to match the original rotor geometry for those 4Runner model years, it pairs with the front-left rotor to reestablish balanced front-axle braking characteristics.
