The R1 Concepts slotted brake rotor for 1991–1998 Toyota 4Runner (front left) is a black-finish replacement rotor intended to restore left-front braking performance. The slotted face helps preserve pad contact by clearing surface debris, making this rotor a practical choice when servicing the front-left corner on compatible 4Runner models.
