Hi, There is a thread in the 911 forum regarding air flow and merits of holes/grills being made in the rear of our cars. I came across a Pic of the GT3 rear with the vent. Does anyone know exactly what the purpose is? http://forums.pelicanparts.com/porsche-911-technical-forum/910200-vent-holes-grill-rear.html
Relieves air pressure build up from under the rear of the car, which can cause lift at speed.
