No NSX does not have it, and i believe 850 and 300ZX have passive setup, wheels are turned slightly due to cornering foreces, that is not 4ws
Do not know about the NSX and the 300 ZX but the 850 CSI is not a passive setup. The Aktive Hinterachs-Kinematik (AHK) of the 850 CSI had a hydraulic system . Turns the rear wheels (above approx. 40 km/h) in the same direction as the fronts. The system was developed on the Nurburgring.

Re: OFFICIAL: New 911 GT3 (991)
I think Porsche's passive system in the 928 countered toe changes in the rear under certain cornering conditions to reduce oversteer in response to chassis/wheel forces. It did not change rear wheel steering angles according to speed and steering wheel position to do what the new system does for handling dynamics.

My concern with the standard steel brakes is that on my Carrera S the rotor looks so tiny in comparison to the rim...
will the GT3 ones (steel) fill the rim more? The PCCB's look like they fill it up almost completely and aesthetically that looks great!
The rotors on the PCCBS's are significantly larger - 30mm front and 10mm rear, I think

You don't need PCCB's. If Porsche felt they were necessary for the overall performance of the car they would have made them standard.
That is not sound reasoning when it comes to Porsche. Some options have been critical to realizing the performance potential of Porsche over the years (i.e. Sport Chrono on the turbocharged cars for Overboost and LSD on some others, -20mm Sport Suspension, some would say PDK for some models, etc.).
PCCB's are totally different (and hopefully for the better) this time around. Not only are they HUGE, they also have a reformulated rotor mixture by some accounts (even look very different on their surface, afaik).

New PCCBs are unfortunately not any lighter then standard brakes. In fact I heard that they are marginally heavier...

Indeed! Nick, that is one hilarious comment and you should know better as you are well aware of Porsche´s pricing strategy. And just consider, how many performance-related options Porsche deliberately puts into test cars...

I was just thinking about 4WS, yes japanese have used it before but only on FWD and 4Wd cars to simulate agility of a RWD car...Porsche is first to use it on RWD car,correct me if im wrong but i cant remember any other such car
I think the Honda NSX, mid engine RWD had it too.
Mitsubishi 3000GT was one of the first to have 4WD.

Both Ferrari and Porsche (GT3) opted to used double clutch transmissions as standard because of the performance value. No doubt the PDK-S cost was incorporated into the GT3 final price. Porsche lost nothing by making it standard.

Re: OFFICIAL: New 911 GT3 (991)
I was not the fastest, but I was the most involved. Convince Porsche that the faithful will accept that without a grumble and maybe they will offer a manual in the GT3. They made the best package they could with the technology available and it did not include a MT. MT has joined drum brakes in the march of time. It maybe lamentable, but that's why old Porsches are so attractive.

That piece reminds me of Kreso's post relaying what his Porsche source is saying, which is that this MT obsession is solely driven by U.S. and U.K. Press. This is nothing more than a "loud minority".

Re: OFFICIAL: New 911 GT3 (991)
macca993:The GT3 used for the track test was on the Dunlop Sport Maxx Race tyre. It's an extreme tyre but also better in the wet than the old Cup+ fitted to 997 GT3 (which in turn is way better in the wet than the first Cup tyre that was fitted to the M3 CSL). Prueninger told me the the Michelin Pilot Cup 2 (which was fitted to the red car in Germany) is a bit quicker in dry conditions but that he'd choose the Dunlop for the UK. Both offer better wet performance than Cup+. These are the only two tyres offered on the 991 GT3.
Thank you very much for those info!
I asked my dealer to get my GT3 with Michelin Pilot Sport Cup 2 but he told me there are not yet available in Porsche options... :(

In the UK at least, I have been informed that 80% of cars will have the Michelins and 20% will get the Dunlops...
Re: OFFICIAL: New 911 GT3 (991)
Can anyone give us more feedback about Ferrari vs Porsche (CCB) brakes ? Ferrari doesn't even bother to do steels anymore, only Porsche does both for some unknown reasons, being the PCCB can't handle all the abuse around the track, are Ferrari owners having issues too at the track ?

Re: OFFICIAL: New 911 GT3 (991)
Marketing?? I guess that's the only true reason they do it that way. Porsche's marketing department is IMO one of the best in the automotive industry (from a business POV that is, especially their business POV...
)
Or..... maybe because they know that some of their possible customers like red calipers more than yellow....

Re: OFFICIAL: New 911 GT3 (991)
I drove a PCCB equipped Cayman S once on a mountainous route and the feel of the brakes was excellent and better than standard. But OTOH Porsche steel brakes never let anyone down.
However, I wouldn't pay the extra cost if it was my car. The main advantage I saw was the substantial reduction in unsprung weight emanating from the ceramics. This advantage has been negated on the new GT3 because the ceramic rotors are larger than the steel ones.
if Porsche offered ceramics as standard the substantial additional cost would have been included in the basic price inflating it further. Ferrari only sell super expensive cars, so another 5 or 10K is neither here nor there.
Porsche customers would definitely get into long pro/anti PCCB discussions, as is the case now with the standard PDK in the GT3.

I do not understand why so many people seem to hate PCCB. It is a great option to have and not only because of looks.
The ONLY two reasons I would not choose PCCB are: I cannot afford it or I track race my car very often. If none of these points applies to you, go for it, you won't regret it.

Mostly US I think. I am in the US right now and got in an argument with a few guys at the pool about manual vs. PDK (they saw a Porsche t-shirt I was wearing and outed themselves as Porsche nuts). In my very passionate conversation with them (mostly in their 20s and 30s), one argument came up over and over again..."only good drivers can drive stick". Spoiler alert, guys...in Europe, every girl and old woman can drive stick. 
This is nothing special, unless you live in a country where most cars have auto transmissions and people just never learned to drive stick. So if people think they are special because they know how to drive stick...they're not. It is difficult to get this out of the heads of people but since I understand the background and the different (car) life in the US, I am not surprised at all. It is a mentality think, same as young people from allover the US coming to Vegas, wearing short skirts (women) they can barely move in and getting drunk until they throw up. Traditions.
Please don't get me wrong, I am not trying to bash the US here, we have our own cadavers in the closet in Europe but I really think this is a mentality thing. Porsche is doing the right thing by NOT giving in to the manual crowd because if they need to compromise over and over again, they cannot actually build the cars they want to build. For those who still want manual, there are other options. Sadly not from Porsche, at least not newer models.
