The R1 Concepts drilled rear-right brake rotor for 2018–2022 Volvo S60 and XC60 is a black-finished replacement rotor tailored to that side and axle. It provides the braking surface needed to decelerate the vehicle; the drilled configuration is intended to help vent and shed debris compared with plain rotors. Be sure to confirm rear-right fitment for your model year and variant.
