The duct in front of the rear wheel is interesting.  It is interesting because it doesn't feed any sort of cooler directly.  So what's its primary purpose then?  This duct takes air in to fill in the base area behind the car thereby reducing drag.  The bodywork "coke bottles" in around the engine and gearbox.
Looking forward with the gearbox removed.  The ducts tuck inside the rear wheels.  Various minor cooling duties are performed by the ducts (brakes, engine bay ventilation), but their primary purpose is aerodynamic.
