To PDCC or not to PDCC that is the question?
So you want the best handling from your 991 S Cabriolet; you spec PASM, PTV+, Sport Chrono etc etc ...
Do you tick the box and add PDCC or not, does the 991 really (really?) need PDCC
answers on a postcard please...

And you want Sport PASM not just PASM. 10mm lower to boot.
PDCC helps extend tire life, too.

Have seen this topic discussed in detail on this and other sites, there seems to be 3 camps;
1 - Puritans who prefer to limit the electronic driving aids.
2 - Those who love electronic driving aids.
3 - Those who feel that there is a marginal gain at the track but at a cost of predictability.
Personally i see Porsche as a drivers car and therefore have no desire to limit my input into the car and its feedback any further than what is absolutely necessary or not an option to deselect.

LexVan, serious question, does it really improve tire life? I don't have it on my car, and have worn out 3 sets of P0's before putting on a set of MPSS (which I am sure will be worn out soon too). My tire wear has been surprisingly even across the width of the tire, and even front to back, even with a fair amount of track use. I was expecting to wear out the outside shoulders, but that has not been the case.
By comparison, my E36 M3 with -3 negative camber in the front wore out the outside edges much more than the 991S with stock alignment.
Larry, I ordered my car in 2011 (before they were released) and there was not a lot of information on the PDCC at that point. I did not order it on the advice of a race car friend of mine who said it made the car feel a bit odd. He had driven a car with and without. However, I would have loved to drive one with and without myself before making the final decision.
If you have the opportunity to drive one of each yourself, that would be the best thing to do, in my opinion. The folks on the forum who have it do seem to like it.

I'm leaning towards no PDCC or PTV+ ... keep it simple ...

My two cents... I don't think PDCC is a 'must have' option at all, but I did spec it on my recent 991 50th and very happy I did!
I had a 991 C2S without PDCC for around a year prior to this new one and both with 'normal' PASM. I haven't tracked either car and wont so that's not an issue for me.
I specced it because a/ I love the engineering of the solution (with the hydraulic roll bar links), but mainly b/ both more comfort in a straight line AND flatter cornering sounded pretty good to me (stiff roll bar on the bends and weak in a straight line)... even if the reviews were marginal.
Near my house in London are lots of poor roads with plenty of camber changes and potholes, and near my holiday place in the countryside some wonderful twisty roads but still poor quality and broken surfaces. The car with PDCC just seems to ride these roads better, handling the broken surfaced straights with more composure yet cornering very flat. So for me it's working well and I'm happy.

I'm probably the contrarian. Nearly every track report I read suggested it was the leading cause of understeer and when I had the opportunity test back to back on the track I certainly felt it on turn in and power on corner exit. The Porsche rep at the track insinuated the alignment range of adjustment was limited to protect the hardware (no idea if this is true). I ordered with out and after 5 track days in five months of ownership I am very happy with my car which has sport pasm and a track alignment. For a street car only I'd probably skip spasm and PDCC and get pccbs.
