A wing reduces rear lift AND front lift?

There is a graph on the page (scroll up a bit) where they show the effect with and without the wing at 157 mph. Front and rear lift appear to be reduced with the wing up.

 

Doesn't make sense to me. I used to work on Porsches, and my boss flat refused to install a whale tail on any customer's car if they didn't have an air dam too, because the whale tail alone would really make the front end light at speed.

Think what they are getting at is that a high mounted rear wing can reduce front and rear lift. Because the effect of such a wing is to straighten the airflow over the roof of the car to the rear of a fastback eg one like a Z or Porsche 911.

 

In other words the effect of the wing is not just local, it extends forward over most of the roof of the car. By so doing it reduces lift over a significant part of the car, not just the rear.

 

Make sense?
