The R1 Concepts drilled-and-slotted black brake rotor for the rear left of 2020–2025 Land Rover Defender 110 is a fitment-specific rotor that uses drilled holes and machined slots to maintain a clean pad interface. The black finish provides a subdued appearance at the wheel, and the description explicitly lists the rear-left application for Defender 110 across those years.
