The R1 Concepts drilled black front-left brake rotor for 2010–2022 Toyota 4Runner is a vehicle-specific replacement rotor featuring drilled ventilation to help manage heat and water on the braking surface. Specified for the front-left position on those 4Runner years, it restores the front braking surface profile and should be installed with the matching front-right rotor for consistent stopping performance.
