Not necessary for a Turbo. It makes much less difference in Turbo compared to taller Porsches (I would not buy a Cayenne without it). If you live where roads are not bad and do not track the car much, you will not see much difference.

I drive my 991.2 TTS on the street with it off, all the time and in all modes. It's simply too stiff.

Haven't done any laps with the 991.2 TTS on track yet, but even then I'm not convinced the tires are good enough for how stiff it makes the suspension and roll control.

You're saying PDCC makes the ride stiffer? I thought the consensus was that it makes the ride smoother on less-than-ideal roads.

This has been covered in other threads. There is no 'off' button for PDDC.

The console control with the picture of the 'shock absorber' is not for PDDC; it is for PASM. And yes, turning it on, will make the suspension stiffer in all other modes.

MaxLTV

You probably mean PASM button that turns on the stiff/track mode. These P-acronyms are worse than IKEA product names. PDCC is a hydraulic active roll bar that cannot be turned on or off by the driver if the car is equipped with it. PDCC effectively disengages roll bars when relatively straight, making suspension effectively softer, so in general it makes the ride more compliant while reducing the roll to nothing.

Good summary , MaxLTV. I'll try to arrange test drives to see if I 'feel' PDCC.

Ironically the ones who claim to "feel it" the most on the street are already invested owners.

Would you prefer that only those that don't have a feature, don't have a single clue as to how it operates, or have never tried it debate its merits?

BTW, I drove PDDC and non-PDDC prior to making my decision.

NVRANUF

And the gold star goes to you!!!..... for attempting a clue with an off-base inference.

Your comment seems to cast aspersions on observations from those that made a choice about PDDC. If it wasn't mean to cast doubt then perhaps you can explain your original comment?

NVRANUF

Sorry, I was merely commenting on the irony of human nature, that once invested (in anything..) our opinions become slightly less objective in order to support our own choices.

I apologize, my comments were not intended to make direct aspersions toward anyone's PDDC choices. There are no bad choices!

ok, I'm confused...

My 14TTs has a PDCC button. So what happens when I push it? lol

Karl911

YES the TTS does have a PDCC button. ON/OFF , pretty simply to test drive, turn it on , turn it off, the difference with the PDCC ON, the car stays flat.

I bought it because after I test drove one, I felt the difference...and I liked the outcome.

It's odd that you imply that those who are not invested in it, would be less vocal about it.

What else would you expect exactly, that someone who doesn't have the option would rave about it? Wouldn't that be contradictory to human behavior?

I don't know about you, but when I'm buying a 200K car, I'm not really thinking about spending more or less on options, or trying to justify the expense of the option. If that were the case, I wouldn't be dishing out 200K in the 1st place.

I assume you didn't buy it because you were concerned about the additional expense. That's how your post really reads.
