If you’re the sort of person who has been poring over the photographs shot through the fence at Brunnchen corner on the Nurburgring, you might well be aware that Porsche has been experimenting with a number of divergent aerodynamic packages for the 992 GT3...................
By fitting a swan-neck rear wing, they were able to claw back 16 percent of what was looking like a 34 percent loss of downforce through downsizing the wing.
In other words, Porsche may well realise a downforce benefit of somewhere in the region of 16 percent by fitting the swan-neck.

WHY A SWAN NECK?
Ever wondered why aircraft sling the engines under the wing instead of on top? That’s because on a plane, the top side of the wing is the important part, speeding the air, creating low pressure and thus lift. That area needs to be uninterrupted. Think of a racing car wing as an inverted aircraft wing and you begin to wonder why it took so long for items with unencumbered undersides to appear.
