The R1 Concepts Geo-Carbon drilled-and-slotted brake rotor is a direct-fit replacement for the rear right position on Porsche 944 models (1987–1989), excluding Turbo variants. It carries the drilled-and-slotted Geo-Carbon surface specified for that application and is offered as a vehicle-specific rotor for brake service or when matching the original drilled-and-slotted configuration during replacement.
