The R1 Concepts slotted brake rotor for 1999–2006 Kia Optima (rear left) is a black-finished slotted unit listed for that application. The slot design helps clear pad deposits and encourages heat dispersion to help maintain consistent braking behavior under regular driving. It provides a simple, vehicle-specific option when replacing the rear left rotor on supported Optima model years.
