>> A type of drag that is often ignored in these aero conversations is pressure drag. Pressure drag is caused by the airflow curling in on itself behind the vehicle, causing a low pressure area that 'pulls' the car backwards.

This would explain the down tilt in the test picture and means that the GTS wing (small, not in the air flow) acts more like a spoiler, rather than an actual wing to generate down force.
