I think it would be a good idea to compile some statistics on the wings available for 996's and the amount of downforce they can produce, as well as other important statistics which would be considered important to "go faster" so to speak.

Once we have compiled a bunch of data, I will put it toghether in a table and post it online.

I will begin searching for information and filling it in as i can get it, but others, please chime in if you have any data to contribute as I would like this to become a comprehensive and informative thread.

Please post information in the following format:

Manufacturer
Name Of Wing
Price
Weight
Material of construction
Angle of Attack
Downforce produced at X speed
Other Notes (other comments you would like to make regarding the wing).


An example of such would be something like the following:

Porsche OEM
GT3 RS (Street Car) Wing
2150 Euro
Weight: xx lbs alone, xx lbs when mounted to base/decklid
Angle of Attack: 0deg stock, 4 and 8 deg shims available
Downforce produced: ??????
Other notes: Available on european GT3 RS street car. Aftermarket replicas available in Fiberglass. Other personal comments on handling effect go here.


This is a pretty good list of wings I think are popular and worth collecting data on:

Porsche Aerokit I (99-2001 996/GT3)
Porsche Aerokit II (2002-2004/5 996/GT3)
Porsche GT3 RS (European Street Car)
Porsche GT3 "CUP" Car Wing (2002 or so cup cars)
Porsche GT3 RSR (i think the wing was longer on this compared to the cup car version because of the wider body)
Porsche GT2 (996 Turbo/GT2)

Mashaw GT2 Wing (aftermarket for 996)
MISHA GT2 wing (aftermarket for 996)

RUF RGT Wing (99-2001 996/GT3/RGT)
RUF Ducktail Spoiler


I think that covers the most common wings seen on 996's that are pushed hard. I'll cross post this on rennlist/renntech/6speedonline in the interest of speeding up data collection.


Here is the formula for the calculation of downforce:

D = 0.5 x (WS x H x AoA) x F x p xV^2 (in other words V squared)

Where:
D is downforce in newtons
WS is wingspan in metres
H is height in metres
AoA is angle of attack
F is aerodynamic coefficient
ρ is air density in kg/m3
V is velocity in m/s2

 

Are we gonna have a quiz on this later ?
