The R1 Concepts drilled black rear-right brake rotor for 2010–2022 Toyota 4Runner is a fitment-specific replacement rotor featuring drilled ventilation to help manage heat and surface moisture. Designed for the rear-right position on those 4Runner years, it complements the rear-left rotor to maintain even rear-axle braking performance when installed as a matched pair.
