Hi everyone!

I'm looking for technical data for 997 GT2 car. Up to today, I only have some basic data from Porsche brochure and some aero data. What I'm looking for mostly, are:
- suspension alignment. Something like Mikelly from Rennsport forum provided for his 996: CLICK_ME
- ride height (and adjustable range, if applicable) front/rear
- suspension rate or wheel rate for front and rear (I prefer susp. rates).
- drivetrain losses
- brake balance (for PCCB and iron-cast if both have different balance settings).

- spring and damper rates (or at least part numbers, so I could contact with manufacturer and ask for data)
- front and rear anti-roll bar rates (in N/mm and if adjustable, then at what range)

- CG (center of gravity) and at what ride height

This one can be hard to get but maybe some of you have access to such data. That is: ackerman, anti-dive and anti-squat, roll center height, bump steer, roll camber rate, bump and droop travel front/rear, kingpin inclination, scrub radius, trail... everything you can provide, will be very welcomed

I wouldn't mind if someone could provide me workshop manual for the car

What for do I need all that stuff? I'm working on such car for rFactor simulation. I noticed, that there are no road going Porsche cars for that sim and I'd like to change that ;-)
If some of data is umm...not meant to be provided on the forum, then please PM me ;-)
Of course I'm looking for stock 997 GT2 car and prefer default factory settings.

EDIT:
What I have:
- static weight balance: 39/61% or 38/62% (or 33/67 (37,6/62,4) for TB993tt's car with no fuel (full 64L tank) )
- Cd = 0.32 (from official brochure)
- fA = 2.05m2 = 22.066ft2

@200kph (123,4mph) that gives theoretical 1224.42N (275,26lbs) of aero drag
FWIK, @200kph the car has total downforce of 9+29 = 38kg = 372,78N (83,8lbs) with a balance of 23,68/76,32% F/R
- based on the above data, L/D is 0,3:1

- engine cutoff @6750rpm
- gear ratios (1-6; final): 3.15; 1.89; 1.40; 1.09; 0.89; 0.73; 3.44

- stock diff. 28/40 (power/coast)
- differential preload same as in GT3: 13,14Nm?

- steering ratio 15,0:1 (or 17.1:1-13.8:1, variable)
- steering wheel lock-to-lock: 2,6 turn = 936deg.
-front/rear track: 1515/1550mm

- toe-in front/rear: 5'(+/-2') / 13'(+/-2')
- camber front/rear: -1*30'(+/-5') / -1*30'(+/-5')

Hi Marek
All I can help you with:
Weight balance of my car as weighed with full 64litre tank no passengers in standard trim was 37.6% front and 62.4% rear. Note my car is quite light, the majority of road specced GT2s come in nearer 1500kg.


I can confirm that Sport Auto quotes the frontal area as 2.05sqm
Engine cutoff is 6750rpm
Drive train losses on a Maha chassis dyno on standard car were 99PS for my car so 448PS to the wheels (most GT2s run around 10PS more than the quoted 530PS)
I have the Sport Auto Supertest as a PDF file if you email me through the PM system.

Thanks! Message sent.

I also updated my first post with some new info.

Thanks. Added to first post.

Correct your link (have "http://forums.rennlist.com/" in front of the proper link)

EDIT:
That "Product Info" document is great! Many valuable information gathered in one PDF!
