The R1 Concepts Geo-Carbon drilled-and-slotted rotor for 1990–2006 Infiniti G20 (rear left) is a single replacement rotor with a Geo-Carbon friction face and a drilled-and-slotted surface. The drilled holes and slots aid heat management and pad cleaning, and the description clearly identifies this item as the rear left rotor for the G20 across the listed years.
