I would love to see how a 997 Turbo RUF 550 or another tuned but NOT suspension modded car performs on the Nordschleife. I suspect a time around 7:40 which would still show the huge advantage regarding the GT2 chassis.

Apparently Porsche took the criticism regarding the GT3 and Turbo chassis very seriously. I suspect that the improvement(s), mainly in the front axle region, will make it to the GT3 and Turbo too, maybe with the facelift.

Christian,
PTM is 997 Turbo problem, not chassis(PASM). Look at wet handling numbers... GT2 is way faster with the same Cup tires...

Andrej,
I suspected that sceptics like the one above will occur...
NO Men in Black influence Gents! GT2 is simply that fast as you will see very soon since different example of GT2 achived some excellent time around Oschersleben track(soon in Auto Bild Sportscar edition)...
Of course we knew it was going to happen. I just find it funny that some people won't budge no matter what. I could care less, frankly, as my buying target is the 997 Turbo, but the pigheadedness of some people never ceases to amaze me.

as you will see in forthcomig issue of Auto Bild Sportscars edition even 32.6s in possible...

Jim,
He was probably reading my Auto Zeitung GT2 test report were AZ test stuff claimed that there is still small turbo lag...
BUT, according to my Motorpresse(company that publish AMS and Sport Auto) friend lag is really pretty small and we can live with it!
BTW, CL63AMG Ring time is 8.14min so, car prefered by WBH(aka VKSF) as a true sportscar is nothing more then Exxon tanker with nice straight line speed...

Kreso, The only thing quicker than a CL63 in the US is the depreciation of a CL63. Nothing else can catch it!
And For the GT2, a small amount of lag would mean absolutley nothing. Its scary fast and really well developed. And when it comes to "speed feel" no other car maker can match Porsches recipe.
FWIW.. Corvette is "partially" revealing the new 650hp ZR1 at Laguna Seca Raceway this weekend. I believe they plan to do speed laps as a warm up for fans at the ALMS race. Also, the new ZR1's get leather interiors from Germany to match their Porsche sourced tire inflator kits. Maybe Porsche would like to source some motors for the Cayenne GTS?
Thanks for all the info on the GT2. They are apparently already all pre sold in the US.

RC, can you please ellaborate on the changes of the chasis?
Thanks
For the first time, the 911 GT2 has a toe that can be fine-tuned. This is done through adjustment plates on the bottom
wishbone and results in high steering precision and a stable straight run.
The front axle wheel carrier was redeveloped for the new 911 GT2 in order to improve driving stability.
The new position of the control points for wishbones and the corresponding kinematic changes in spring deflection made it possible to improve the steering and cornering behaviour. The advantages are high straight run and track stability, particularly at high speeds and neutral cornering behaviour.
According to the driver of the 997 GT2 we "met", the new 997 GT2 has a very neutral chassis setup, there is no understeer at all and oversteer is much easier controllable than in previous models.
I was very surprised to see the lack of a PSM Off button inside the 997 GT2. Porsche did a very clever thing, they named the same button SC TC Off instead of PSM Off. It is basically the same thing but the 997 GT2 definetely has PSM, even if Porsche doesn't like to call it this way.
On the GT2 however, turning PSM off (SC and TC Off position) shuts off the PSM completely, it does NOT come on again during braking for example (997 Turbo, 997 Carrera).
The 997 GT2 is basically a 997 Turbo with 997 GT3 chassis.
Basically. The engine hasn't been modified much, only the VTG chargers have been modded, the new expansion intake system is also new (basically allowing to keep up with emissions laws/regulations, to keep fuel consumption as low as possible, not necessarily because of the power gain ) and of course the new exhaust system made out of Titan (very likely because of increased heat, not necessarily because of the weight saving of not even 10 kg ).
Engine is the same, the GT2 has, to my knowledge, the same engine parts like the 997 Turbo, no different conrods, etc.
There is only one "bad" thing about the new 997 Turbo:
the VTG chargers and the very high boost pressure. There is no way to actually increase power on this baby without the need of substantial engine/turbo charger mods. The boost pressure is already very high at 1.4 bar, the current VTG chargers don't really "support" any more pressure.
Meaning: for some people, a tuned 997 Turbo may be the better and cheaper solution, especially for street driving.
Otherwise, the new 997 GT2 is the hell of a performance machine and a lot of fun. Just can't wait to testdrive it, hopefully before the real snow comes.

Re the 997GT2's 0-300kph. If it turns out ~32s I consider that pretty disappointing. With 530PS and that impressive torque curve surely it should be coming closer to the RS Tuning 542PS 996GT2 tested by Sport Auto at ~28.5s ?
Is the downforce slowing it down somewhat

Few interesting comments from the article:
-GT2 is offering the best high speed straight line stability of all current 997 series models. Excellent aerodynamics is the key here with good downforce
-traction is amazing for very powerfull rear engine car. In fact since GT2 is almost 2s faster on wet handling track then 997 Turbo we can get only one conclusion-PTM AWD system is flawed. On wet handling track good traction is more important then PASM setup so, it is really interesting that 997 GT2 is that much faster on the same tires(Cups) then 997 Turbo.
Techart Gt Street Supertest clearly show that PTM system is not SOTA...

If the Gt2 uses different front wheel carriers and adjustable camber arms, it should a relatively cheap upgrade to the existing 997tt's so long as the front axle length is the same

It makes no sense to start the old discussion again. I think all is posted. But I have only one question and I try to ask this as neutral as possible not to generate a bad mood in this thread:
How can it be that HvS achieved after doing 2 laps (according to supertests policy one intro lap and one fast lap) nearly the same lap time as WR (who is imho one of the fastest driver on the planet) who did hundreds of laps with the GT2?
If the lap times of HvS would have been between 7,35 and 7,38 for the GT2 that would sound realistic to me and I would not criticize the supertest anymore.

Here is a potential answer-new 997 GT2 is much easier car to drive on the limit then 997 Turbo(manual with optional LSD). Apparently GT2 offeres better traction(dry track) and high speed stability on straight line and in corners then 997 Turbo. This is the reason IMO. I spoke about it with my friend who works for Motorpresse(company that publishe AMS and Sport Auto).
One 997 Turbo TIP(and TIP version can not have optional LSD) owner said to me that car is pain in the ass for track driving on the limit or near it. Go figure...
