What Wing and Why???

Keep in mind...it's
my hypothesis that this is the reason. It sounds logical enough, push down on the car, aft of the rear axle, and the car will get lighter (lift) up front.
Along these lines...I did a field experiment...ran a GT2 rear wing at 9 degrees of down angle, at about 120 in a sweeper, with 993 RS front splitters (Too small!), the car pushed like a demon. I slowed to about 100 or so. As I was turning in the car, it didn't take the steering input, behaving as if to say, "we are going straight." That experiment cost me about $800 in repairs.
We have been reading for years about matching up spoilers front and rear, or be prepared for understeer or oversteer depending on which end you have inadvertently unbalanced the car.
Damn, it seems like I have too much time on my hands. I had better get back to my chores, wifey on the way home, can't have any clutter!

Quit! I'm having flashbacks!

Great summary posted here on the effects of wings. I have Frere's book which contains the same info. I have always wondered what the effects of a turbo bumper are on aerodynamics, though.

Hey Martin, are you still running the Getty front end? How's that working out? Too much down force or just right?

There are 2 ways to do aero, a complete lid+wing all in f/g or C/F or a f/g(or C/F) wing that bolts to the stock steel lid after the motorized stuff is removed. The stripped steel lid itself is quite light @10#
Unless an intercooler is needed, a steel lid + separate wing is usually lightest

Martin, I'm not singling you out, so don't take this that way:
Someone always post this on the wing threads. I don't get it. The 96 Turbo has the biggest stock wing, yet no front splitters, and no one ever complains about the balance. I can see where maybe the RS wing and splitters were engineered to work together. But the Turbo wing was installed by Porsche on all those cars...
Does the stock Turbo front bumper produce more downforce than the stock NA cover? Or, does the non-"S" Turbo get light in the front at high speed?
Help me understand.
