Not that anyone asked, but since we'er on the subject....
In my book the jury is still out on PDCC style suspension (BMW calls it ARS or dynamic drive). I've had 2 BMWs with it. My 2 cents:
Learning a car takes time; how the clutch behaves, how the car reacts to steering inputs in various circumstances, how the brakes hold up etc etc.. Non-PDCC suspension is linear. You can learn the 'curve' of how the suspension reacts to predict body roll, understeer etc.. The PDCC is not linear in that sense. The suspension gets to a certain point and then sort of freezes (uses as much hydraulic pressure as necessary to prevent further leaning - like a huge bouncer holding someone at arms length).
Positives to PDCC -
the flat cornering feels really good as it generates lots of g force, the system softens in a straight line to theoretically give a more compliant straight ahead ride (this akin to the OP's question about turning the system off).
Negatives - weight, expense, promotes understeer, can feel unnatural when driving at or near the limits
I think that the 911 driver who is occasionally spirited but not a hooligan will benefit from PDCC. But if your into a lightweight machine that might see some track days (that's me) then I would always elect a baseline stiff mechanical setup.
But I haven't driven a 911 with PDCC yet...

I'm not sure Porsche thought people were walking away from 997.2 deals because of the car being too raw. Why should we think that our tastes in sports cars are more discriminating than that of "new 911 buyer"?
I drove the new 991 and it still feels you are strapped to the back of a Saturn rocket. Still raw enough. Engine still feels 6 inches from the back of your neck and shakes you to the bone when cold. </opinion>

Easiest way to accomplish this is to improve the visual impact of the car which I (opinion) feel they did overwhelmingly.

You actually can't get PDCC in the base, only S - so with the 991 you really need to figure out what you want from a standard or S version. We opted for an Cayenne S versus a Turbo and have not looked back. I see the great looking Turbos and I just could not get myself to put 165k to an SUV versus the 125 we did for the S. But what we did is fully load it, PDCC, PTV, Full Leather, Bose Package, Ventilated, Light Package, and more - the car is awesome and really fast enough for these pretty crammed streets. I am really torn between getting the S and base when the 4s come out.
