Any front and rear downforce data?

Any front and rear downforce data?
Does anybody have any factual data or numbers on the extra downforces created by the GT2 front vent and the GT2 rear wing compared to the regular Turbo or Turbo with aerokit?
Thanks
Thanks

From a book called Porsche Turbo The full history of the race and production cars by Peter Vann. In the 996 turbo section chapter 10 they talk aerodynamic!!! Our turbo got a coefficient of drag of 0.31. And you can see the frontal and rear lift....Hope this help!

My guess would be that making the GT2 front bumper functional would probably be a big help. I understand that to make it 100% functional though is pretty involved and quite a bit of parts. Maybe just getting the radiator air flow and bumper vent working right would do the trick.

i have the same setup. i will be testing the aero this yr at 3 half mile events. full functional front gt2 setup with added 997 full underpanels to increase downforce under the car. my goal is to run as close to 200 mph as i can and have it feel solid. im hoping with proper susension dialed in the aerokit rear wing will work well with the gt2 front setup. if not then ill add the gt2 rear decklid

no worries ask away. for some early data i do have the 911precision fiberglass gt2 bumper. its much heavier than i ever thought it would be. if i can find a poly bumper that is a decent buy ill get that. but for now its the glass unit

I have a gt2 fiberglass bumper on my car and I bought it that way but it does have all the gt2 ducting to go with it. Car is very stable at 150+. I am adding a set of Joe's canards though as well to have a bit more front downforce.

cant do the canards hate the look. pwdrhounds addition of the underpanels was a great idea that is unseen and should help add more downforce under the car. time will tell

Yes I do. The canards are things it seems guys like or hate. I've always liked the looks of them and my car it primary to toy. Weekend racing and joy rides. Not my dd by any means

I had my shop install the full 997 under tray, 911Precision GT2 front bumper and rear deck lid & wing.
This was not done to make my car look like a GT2, rather for the aero stability at the track.

Pics and where you can get the 997 undertray? My car has trays everywhere but where the engine is which I think is standard fr the 996 turbos but if the 997 design is better that would be a nice upgrade. I want to do a rear diffuser for me car as well and was looking at a 997 model diffuser. I'm sure I'd have to mod to fit it.
