The thread is titled "RS side rockers in Polyurethane " and is on page two. You can also see the entire kit installed on my car in the "New Car ****!!!!" thread on page one.
GT 3 Tek has a great price on the RS parts and the fit and ease of installation is exceptional.
I set up the group buy so if you have any questions drop me a PM.
Cheers,
Joel Bowman

there are 2 different RS aero packages
@270kph @ stock RS height
the smaller produces 178N of lift in front & 0 lift in back, Cd is .33
the bigger RS/CS package produces from 0 to 178N lift in front & -119 to -713N of downforce in back depending on how the wing is set. Cd is .34 to.36
the stock lid weighs 24#, a complete small RS lid/tail weighs 17.5#, a T/S complete weighs 38#. I need the weight of the RS/CS lid/tail

Trying to see if you guys can give me some advice on what wing to go with eventually to take some weight off the back end, And for the looks.
Please Post pictures if you have a wing on your car and you reason of why you went for it.
Also who makes the best quality aftermarket wings? MA SHAW?
Choices:
Turbo Wing
Turbo S wing
RS Wing
My car is Black with Turbo Twists, But maybe one day BBS LM Wheels.

Why limit yourself to one choice????????
it takes ~ 20 minutes to change from one wing to the other as long as you have the RSCS wing mounted on its own decklid.
The RSCS wing = MA Shaw, its good quality, the other two are P parts.
have fun!
Craig
weight lightest to heaviest = RSCS, Turbo S, Stock

this photo does NOT show the C shaped outer wing that bolts to the tailbase.
Turbo wing does not equal Turbo S wing.
have fun

yes, you want the minimum lift(or even negative lift if possible). Note that the very aggressive RS/CS package which can go down to 0N lift in front, but also depends on how the rear is set up so can also go up to ~the value of the plain RS package.
All of these #s can be improved by lowering and raking the car.

The terminology Bill uses may be confusing to the non metric system folks; it was to me when I first read this data in Porsche's Dervice Information Technik '96, 911 Carrera RS, bulletin WKD 499 620. You may want to know how to convert N into Lbs. Multiply N X .2248 and you'll have Lbs. All the data Bill supplies below is based on the 993 cars at a terminal velocity of 270 kph, which as we know multiplied X .621371192 to arrive at 167 MPH, not a speed much of us will ever see. Therefore, you will NOT experience the lift and downforce #s stated below:
Bill writes, "there are 2 different RS aero packages @270kph @ stock RS height the smaller produces 178N of lift in front & 0 lift in back, Cd is .33 the bigger RS/CS package produces from 0 to 178N lift in front & -119 to -713N of downforce in back depending on how the wing is set. Cd is .34 to.36"
Let me translate, ....there are 2 different RS aero packages, the 993 RS and the 993 RS Club Sport. Both packages utilize the same side skirts, ones that we have come to call 993 RS side skirts. @167 mph and @ stock RS ride height, the 993 Aero Package (993RS wing and 993 RS front splitters) produces 40 Lbs. of lift in front & 0 lift in back with a resulting Cd of .33.
The bigger 993 RS Club Sport package having (993 GT2 front splitters and a GT2 adjustable rear wing) produces from 0 to 40 Lbs lift in front, with lift increasing in response to increases of wing down angle. As you dial increasing amounts of down angle into the rear wing we see at 0 degrees down angle in the rear, front lift is 0. At 3 degrees rear down angle, front lift has gone to 13.2 Lbs, at 6 degrees of down angle, front lift increases to 26.7 Lbs and at 9 degrees maximum rear wing down angle, front lift is up to the same as a 993 RS aerokit package, a whopping 40 Lbs of lift.
In addition Cd (Coefficient of drag) increases as well, .34 ,34, .35 and .36 while at the same time, rear down force increase in response to an increase in down angle, from -26 Lbs, to -66 Lbs, to -120 Lbs and concludes at 160 Lbs of downforce, assuming you have the HP to reach 167 mph with a .36 Cd. Please note thata car with a .36 Cd is not exactly slippery.
IMHO, the front picks up increasing lift as the rear wing's wing angle is increased, or so it would seem.
In conclusion, I have had the 993 RS package for a number of years, Getty Design tail and front splitters and side skirts for Gert Carnewal. These are front splitters and RS tail are coming off to be replaced by a Getty Design GT 2 rear deck and 993 RS CS front splitter, brand name and pics to be revealed after I get some feed back from the paint shop as to fit and finish.
As always, Bill Verburg is an invaluable source of information. His posts are always informative.

Unless an intercooler is needed, a steel lid + separate wing is usually lightest

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#

Bill and Martin - I understood the Newton unit, but didn't fully understand the correlation between rear down force and front end lift. Thank you both for the explanations
