Couple questions about PDCC.

One: Does anyone know if the cars that Porsche uses for the sport driving school at Barber are equipped with PDCC?

Two: For those who track their cars, what's the verdict on PDCC?

Three: General comments about PDCC are welcomed too.

Thanks.

PDCC increases the dynamic range of the car: more-comfortable on crappy roads but corners on smooth roads as if it has a go-kart suspension.

PDCC = hydraulic stabilizers. They are unattached in a straight line for a smoother ride but hook up again as you turn for flatter corning. I have it on my car and enjoy it with no problems. Disclaimer I don't track my car. There is a video by Porsche comparing lap times with various suspensions and PDCC is the fastest. I am not sure about track reliability but there are some older reports of PDCC failing at the track.

#3 I like the way PDCC anchors the car in turns. I only have 2 DE events under my belt and have zero track time without PDCC so I cannot compare. I have seen comments here from some self-described "purists" that the PDCC feels artificial and numbing because it works so well in removing body roll. I suppose I am not a purist because I like the way it provides more control. For every day driving around town and on the freeways, it may not be necessary but does allow you to lay it out in the cloverleafs. I hit the button on occasion just to keep hydraulics lubricated In hindsight, if I had ordered the car, I probably would not have checked the box and would have spent the money elsewhere.

If you don't have PDCC or buy used without it, get this

FWIW, the 991 GT3 does not come with PDCC.

More for weight savings than performance, from what I am told

I’m not experienced enough to say what’s better PDCC or sans but my experience is on regular roads I don’t really feel much difference in handling except that when hitting rough spots on the road, the PDCC is alittle more sharp and jolting on the bumps compared to normal. I find the handling and amount of body roll about the same in either mode.

On track ive only driven PDCC on so cant compare but the car really shines in terms of managing stiffness and body roll without being too overly crazy.

I did have PDCC failure warning come up twice when cooking turns too hard and stressing the suspension. Stopped and restarted the car and the car was fine. And since had one more full day at the track after with no further issues

FWIW I have tracked my PDCC equipped 991S for four years (8-12 events per year) with zero problems. I am extremely pleased with the way it works.

Thanks guys.

I've been wondering about PDCC vs RAS, or a combo of both. Somehow PDCC seems more gadgety to me than simply a steering mechanism, like it might take away more of the connection with the road and driving experience than RAS.

PDCC definitely tightens up the chassis of my Turbo S. I find that it significantly reduces body roll, gives me better feel in the steering and overall I use it at the track even on a relatively bumpy track. On the street it has limited application, it's a bit jarring on anything but smooth roads, and I think the suspension only gets loaded enough to give you the feel back if you are close the limits - which isn't so good for street use. I use it occassionally on street, if I know a particularly sweet corner or something, but it's always temporary.

Points for effort, Worf. No matter how many times or how clearly its stated a lot of people still think the button turns PDCC on and off.
It should be a fairly straightforward thing to understand. Especially compared to this: http://www.roadandtrack.com/new-cars...pension-works/
