The R1 Concepts drilled-and-slotted black brake rotor for 2000–2008 Audi A4 (USA/Canada) (rear left) is a direct-fit replacement rotor that restores rear braking balance and pedal response. The drilled and slotted surface assists heat dissipation and pad debris removal, which helps maintain consistent friction and resist fading during repeated stops. Ideal for routine service when rear rotors show wear or scoring.
