992 CS - PDCC, PASM, RAS - Road car.
Discussion
I specced my C2S with the options you mention, RAS and PDDC, PASM and PCCBs. Coming out of a 991.2 GT3 I wanted to get as close as I could to that and haven't been disappointed - it's a really excellent chassis. PASM off is more comfortable btw. On, it sharpens things up considerably. The PCCB's are the best I've experienced in any car.

I've got to finalise the spec of my 992 Carrera S in a few days and am still in two minds as to what to go for.
Please can someone more knowledgeable help me understand the difference between standard suspension, PASM and PDCC!
Please correct any of this information if I'm wrong but this is what I understand as was explained by my instructor on the Porsche experience day - although he was wrong about some other things that I knew not to be the case!
PASM is lowered suspension by 10mm, and with the PASM button off the suspension is softer than standard, when you press the PASM button it is stiffened to the same amount as the standard suspension?
(I would have though button odd was standard and button pressed was harder than standard but that's what he said so please correct me if I'm wrong)
So I would like PASM not for the lowering although I'm fine with that, but for the extra comfort with the button off - IF this is the case!
PDCC is mainly to limit body roll and can be specced with or without PASM but must be had with Rear Axel Steering?
RAS seems great on the experience day track but I'm concerned it may make the car feel too competent as a road car only?
I asked in the 992 Essential Options thread about PCCB and I think I will spec them now (in black).
Any advice appreciated!
I’d save the cash on PDCC as it makes it feel far too capable. I’d do without RAS as well although I’ve not tried a car without. My 4S just felt a bit dull unless you were 100% on it. Please can someone more knowledgeable help me understand the difference between standard suspension, PASM and PDCC!

I tried cars with and without PASM before buying my 981... with PASM. It would be amongst my top options.
PASM off is more comfortable than standard. PASM on is harder than standard. I generally use PASM on when going at slightly higher speeds on the motorway.
PASM off will react if you do some sporty driving and alter itself toward the "on" setting without actually changing the button setting.
PASM on will react to relaxed driving by softening the suspension itself without actually switching the button off. It reacts to your current driving style. Clever stuff, and it really does do this.

PASM. All Carrera S have PASM fitted as standard. The choice is between the standard fitted PASM and the lowered suspension with PASM. PASM 'off' gives the more comfortable ride, although the idea of 'off' is misleading as PASM is always active. Selecting 'on' causes PASM to adapt its behaviour to deliver a more sporty chassis.
As a consequence of the above PDCC always comes with PASM. PDCC adapts the car's roll stiffness according to what the car is experiencing. Roll stiffness is increased when cornering and is less when travelling in a straight line. This leads to a more supple straight line chassis and a stiffer (in roll) chassis when cornering. This improves the straight line ride.
Ride quality is very subjective. My car (992 CS) is equipped with lowered PASM and PDCC and I find the ride comfort to be fine, but I like a firm ride.
RAS is a personal choice, I like it, other's don't.
I have PCCBs fitted (with black calipers) and they are excellent. Easy to modulate braking from very gentle to just before ABS intervention. Great feel.
Torque vectoring is standard. Manual cars (will) get PTV, PDK cars get PTV Plus.

All 992 911s have PASM as standard - the optional PASM sports suspension on the Carrera S is lowered by 10mm. There is no passive suspension option. Please can someone more knowledgeable help me understand the difference between standard suspension, PASM and PDCC!

PASM is always operating - it is not on or off. You select normal or sport. Sport is firmer (you press the button to select sport).
I spent my £ upgrading the stereo rather than adding PDCC, and I did add RAS - and maintain that it greatly helps in the Waitrose car park.
Car also handles brilliantly so I assume the rear steer does some magic there, but it's been a while since I've driven one without it to even remember.
I still think there's no point adding ceramics unless you'll really intend to do enough miles to care about the extra life.

PDCC doesn’t seem to be a popular option, especially amongst experienced 911 drivers, who prefer a small amount of body movement to give the feel of weight transfer.
Only tried it at PEC and wouldn’t be my choice.
I have had PCCBs and loved them. They would be on my list for a host of reasons. I think they elevate the car. Most critics are people who don’t have them.
In the used market they may not add value to those who don’t want them, but they do add value fir those who do.
RWS I have only experienced during a brief drive in a GT3 and couldn’t really detect it as an individual chassis component.

I could not imagine driving a 911 without the essential feeling of having to understand how to transfer the weight, its what makes the 911 special for me.(which reminds me, need new tyres this year !)
It is possibly best summarised as there is not a bad option, only different ones.
I can't imagine anyone suggesting that PASM is anything other than very good, I had this on my previous 911 and used it far more than I was expecting to. My current 911 has PDCC and I must say I think it is fantastic. However, it does alter the interface between driver and when in sports mode the car is very flat so I do recognise that this 'feel' will not match everyone's taste. I drove cars with PDCC and PASM back to back at the Porsche Experience Centre and have been a fan of PDCC ever since.
To return to my original point, there is not a bad choice regarding PASM v PDCC, just different flavours of the same excellent recipe. Sometimes we can forget just how good a 911 is in all its guises.

Interesting and I'm not going to be driving a 'new' 911 anytime soon, but do any of these systems kill the understeer you can get in a passive 911 ?I can't imagine anyone suggesting that PASM is anything other than very good, I had this on my previous 911 and used it far more than I was expecting to.

In a 997 (and my 3.2) especially on the track, you need to work the weight shift to kill understeer and get it to turn in, drive a passive 911 wrong and it won't do what you want. Do these systems change that significantly ? I imagine they are incredible systems, but is any 911ness removed ?
Its amazing how much a 3.2 and a 997 GT3 are similar in their responses (the GT3 does it so much faster though), are they engineering this out for the mass market in the newer cars ?

Based on my experience with 991.2 and 992 the RWS reduces understeer..This is much more significant on the 991.2 compared to the 992..However my 991.2GT3 RS was understeering more then i expected when i had it on track about a month ago.In a 997 (and my 3.2) especially on the track, you need to work the weight shift to kill understeer and get it to turn in, drive a passive 911 wrong and it won't do what you want.

Bet that was a fun day.So you still have to get the weight on the nose with a bit of shading the brakes. I'm no expert but I love the fact that even after 13 in a 911 it still feels different to anything else i have driven.
