Ducktail or wing for track use?
My 964 basically becoming track only more or less... o want to reduce weight from the rear lid/spoiler assembly so the original has to go.
I have a ducktail in glassfibre but not sure that aerodymacally it would be effective on track. I know it’s a spoiler and not a wing so provides no actual downforce as such, just eleiminates lift. I don't like the fact it will create drag but no downforce.. Will it be as effective aerodynamically as the standard electric wing at least? Or should I use a GT3 type affair instead?

Other than the ducktail looking great it does little over the stock wing other than save weight. The RSA style wing does help but it weighs about 6 pounds more than stock motorized wing. I noticed much greater stability at speeds above 120mph and it also helped more with cross winds. The Bi Wing is the best bang for the buck. light weight and adds downforce while reducing lift.
You might consider going with a Bi wing for track and switching it back to the ducktail for the street. You might consider some form of splitter up front as well or dropping the front end a little if not.

I did not thin k the Ducktail would be better than the current electric spoiler.. just dont want ti to be worse. I do have a feeling that it might be less aerodynamically efficient but then a large part of the function of our wing is engine cooling..
This is one i was considering..

Thanks.. which one is the bi wing??

they don't seem to have one. here is a link to the one I have. mine needed to be modified to allow it to close over the IC but should be a direct bolt on for you.

Here's a summary of the various aero packages that were factory installed

This wing is more of an early 930 wing will do the same as the RSA style but I believe the RSA style sits slightly higher and doesn't have the ribs.

Bill,
Are these factory published numbers? Something is odd about the RSA. This is contrary to most info I had read. Also are the 3.8RS numbers with or without front splitters?
