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

Once bid on e-bay for a gemballa rear lid for a 996 turbo. The guy selling it said the reason he was selling it was he sprintted the car here in the uk & with the standard 996 turbo lid he got 192 mph. With the extra downforce of the gemballa lid he was down to 187 mph so he put the standard 1 back on. The gemballa went up for sale. Have you included the 996 clubsport lid i had 1 but sold it. That had a carbon blade fully adjustable for 0 to 55% download. Trouble was too much rear download makes the front light so the road holding suffers.
