Default PDCC on a 2018 GTS: Yes or No?

I've got a doubt concerning my build. After discussing PDCC with another knowledgeable driver who just took delivery of his 2018 GTS and passed on PDCC, I wonder whether it is a buy.

I am planning on rear-wheel steering either way.

I am curious to hear your real-life experience with PDCC, and whether you'd include it in a DD build. My car will be a 7-speed Coupe. Thank you in advance!

PDCC allows the suspension to work independently when driving straight. So the ride is improved. If you have smooth roads then skip it. I have it on a 991.1 and a PGTS and would not go without it, for street driving. But It does keep the PGTS remarkly level in high speed turns at the track. Probably a bigger benefit for heavier vehicles.

I've had both and live in NJ and drive to NY. My current 991.2 doesn't have it... I don't miss it. Can I tell on an off ramp when being aggressive that the car is leaning a bit, yeah. I kinda like that feeling. Was the car flatter with it. Yes... I built a car for September delivery and it doesn't have it... but if $$ no object get it. Is it a must, I don't think so.

What about PASM plus sport suspension?

will you need front end lift on the GTS if you lowered the suspension?

Thanks for the response so far and great question.

Yes, I am getting SPASM and front-end lift. Mostly for gas stations, parking garages, etc.

I found the ride quality, at least in my area, significantly better with the PDCC. I'd definitely get it again. And I love the flat-cornering sensation. It's the closest I'll get to feeling like Sebastian Vettel!

I've had both. I would skip it and save money. I even tracked cars with and without it. The sensation is slightly flatter but lap times were no faster.

I have had PDCC on both the 991S's that I have owned (one PASM and the current one SPASM) and love it. Very comfortable ride and I like how flat it is in cornering in AX. Some folks don't like it (artificial feeling?) but YMMV. If I was ordering a car, I would spec PDCC.

have on my 991.1 PASM Cab and love it. Would recommend more for a DD than for a track car.

I can feel my PDCC at work in the quick " left right left right etc" small radius rising / dipping S curves of the many mountain roads here in NorCal where my car is not being asked to lean and set itself for a long higher G higher speed sweeper as on a track
...it gives me a sensation of driving a lighter car with quicker flatter reverse direction transitions
and as others mention , PDCC effectively decouples the left and right side of susp vs std sway bars when driven purely straight ahead , so that my local pock- marked freeway ride is calm and smooth
my current RWD 2016 991 GTS cpe also has the lower -20mm SPASM susp but I noted an even greater effect of PDCC on my prior heavier AWD 2013 991 C4S cpe which had normal -10mm PASM susp

YMMV ...it is a desirable feature for MY driving / road conditions as reviewed ...if I lived where my spirited Sunday AM driving were not curvy and local straight highways/freeways are paved well -whether tracked or not - I would then skip it .

All very helpful. Thank you. Sounds like it may be a good feature for DD ride quality, although some don't miss it. I think the GTS with the SPASM will be pretty stiffly sprung, so I may consider PDCC. I'll drive 991's with and without when I "spec" the order later this month.

my 2016 991.1 GTS Club Cpe with optional SPASM and optional PDCC never feels stiffly buckboard sprung nor generate any squeaks or rattles ...even with Sport Plus activated , whether on uneven lumpy neighborhood roads at 10-25 mph or at " speed " and IMO is factory calibrated by Weissach to feel " high performance with sophistication " with any allowed std/opt susp option combos and not any more " extreme " ... BECAUSE GTS , NOT GT3 , lol !

I have a 991.2 C4S with PDCC and SPASM and RAS and 20" wheels at 30/35. It's a daily driver typically in sport mode all the time. I only turn off the sport chassis button on the console if I am on a really bumpy road - and I can really tell the difference in those cases - but usually the ride is fine. I don't know how much the PASM contributes vs PDCC but given how much I have heard complaints on these forums about firmness and rough ride I suspect PDCC is making the ride smoother. Plus, the real benefit of all of these things is that the car is incredibly flat on the turns. A+++ will buy PDCC again.

PDCC on my GTS and did a 250 mile drive yesterday on motorways, twisties, on and off a car ferry, plus good and poor surfaces. Even the Mrs in the other seat remarked on the comfort and lack of drama.

I haven’t driven a GTS w/o PDCC to compare but mine rides better than a C4S I tried which didn’t have the option ticked.

Whether you think it’s worthwhile or not might depend on how you like sports cars: do you need to feel every bump in the road to get your money’s worth or do you like a bit of comfort to go with the performance? As both are meant to be improved by the option it was a no-brainer for me...

Yes. On my TTs more comfortable ride and the car feels lighter and more agile in quick left / right turn transitions.
