The R1 Concepts drilled brake rotor for Jaguar XJRS (1983–1993) rear right is a black, drilled replacement rotor that renews the braking surface at the specified wheel position. The drilled pattern assists cooling and water evacuation to help maintain consistent pad contact and reliable braking feel during routine driving across those model years.
