what MY?
trying to piece together information if what my SA told me (that PDCC on gts is not an approved option per production planning department which is why my my24 cab order pushed out by 2 months)

PDCC and RAS is an age-old debate on Rennlist, almost as divisive as PDK v. MT. Almost.

Let's rephrase your question.

Instead of asking whether it is "necessary" for normal use, let's ask ourselves how you would like your 911 to drive and behave during normal use.

If you prefer your 911 to drive more like traditional 911's, where the car is a bit more lively around corners and you want to feel more connected to the car (as best as you can given the 911's suite of electronic gizmos and nannies), then bypass RAS and PDCC.

But if you prefer a 911 that not only looks like a modern GT car (i.e., a grand tourer) but also drives like one -- planted, insulated and synthetically sharp -- get the RAS and PDCC.

There's no right or wrong, or "need" in either instance.

Just what you want out of your 911.

But What about the daily comfort aspect? Not that a "regular" 992 is harsh at all but does it make a NOTICEABLE difference on the street?

Yes, as I posted previously, PDCC with make the ride more comfortable by reducing the roll stiffness when driving in a straight line.

I didn’t get PDCC on my GTS and I don’t think it’s needed. On the race track the car handles amazing with rear axle steering and the body roll is minimal (I got 1.7 G on the stock ps4s on the track) . I think if you’re tracking the GTS it makes more sense to get a track alignment than get pdcc. Pdcc also adds 40 lbs to your car as well. I would skip it.

No. Also, research the maintenance and service requirements for PDCC to factor into your decision. System was originally designed for Porsches top heavy SUV’s such as Cayenne. 911 not top heavy at all with flat six boxer engine and transaxle, driver and gas tank sitting low.

Aside from replacing the PDCC reservoir at 6 year / 60k, what else is involved?

I made a similar transition except the other way around. I went from slick top 992 GTS with PDCC and RAS to Glass moonroof 992 GTS w/ PDCC and RAS. I can say the moonroof takes away from the feeling the car has, doesn’t feel as sharp or precise as the slick top did.

If you want a more compliant ride on the street and maximum lateral grip for the track get PDCC. I would not say PDCC has a synthetic feel. PDCC just works better than a passive anti-roll bar the same way independent rear suspension works better than a straight axle.

Many of these kinds of questions really depend on what your expectations are. Ride comfort is very subjective. You're coming from a Panamera and a Macan, both vehicles that have what I would describe as a comfortable ride, but noticeably firmer than, for example, an E-class Mercedes. For a sports car, the 911's ride is relatively comfortable and compliant, but for someone who has never owned sports cars, it could very easily feel harsh and tiring, particularly on the crappy roads that dominate most North American markets. For some, a 992 GTS with its standard suspension perhaps tilts too far to the "unforgiving" side of the equation; for others who are used to a 991 GT3 or similar track-focused sports car, a GTS might feel surprisingly comfortable and compliant.

Also, the answers you get are very often skewed to the preferences and choices of the respondent. People with RAS and PDCC are more likely to tell you to get these options. Those without are more likely to tell you they're not necessary. The only real solution is a long test drive over many different road surfaces with as many combinations of these options as possible.

Final point: Porsche does not make a bad 911. The most basic 911, as it comes from the factory, is light years better to drive than almost anything else on the road. The main function of most of the options is to extract more profit margin from Porsche buyers, not necessarily to fundamentally improve the car. I'm a sucker for many of the options, but there are definitely diminishing returns, particularly for options that are suspension / chassis / steering related, since these are areas where the basic Porsche DNA already results in a fantastic car.

To the OP, if you are purchasing a GTS (with the firmest spring rates of any non-GT 992) and concerned about adding PDCC to improve 'ride comfort', then I'd respectfully suggest you consider a 'lesser' model.

I have seen articles in the past that PDCC makes the ride feel so artificial that people, both drivers and passengers have complained of extreme motion sickness. I have no idea how widespread this phenomenon is, but probably not worth the risk on a car that is going to be amazing without it.

dhirm5

Oh please. I've been driving a PDCC+RAS car since 2017; nobody has ever complained about motion sickness. This is utter nonsense.

Save the money, do what you prefer, don't justify it by spreading FUD.

Just get a C2S if you want the ride to be more comfy.

GTS suspension set up very different. I love it because your more dialed in similar to my 2018 GT3 but some may consider it a little harsh
