So I test drove a 991 with PDCC yesterday and wow. I did back to back C2S with and without PDCC and I made the same spirited turns. I did notice how flat it felt during the turns with no tire screeches whatsoever. Wow. I'm pretty impressed.

 

The C2S without the PDCC, did it have the SPASM?

 

From what I recall on the sticker, I don't think it did. You think it was more of the lowered stance and springs?

 

Not exactly the lowered stance and spring but the stiffer sway bars and springs. In my opinion, PDCC is great for,lets say Cayenne, with a high center of gravity and will lean over no matter what. The SPASM setup, which is flat enough on turns, I think is great on the track as you can read the car well as it approaches the limits while the PDCC might give you an artificial feel of what is really going on.

 

Frank, I'm glad you got to test the cars back to back.
From personal experience PDCC is phenomenal! The combo to go for is PDCC and SPASM. I have tried one without the other and there is a noticeable difference.

BTW, I really don't want to get into a debate about PDCC with BlackPepper or anyone else and will respect their views but would disagree. PDCC is transformational on the non GT 991's and provides characteristics that are quite different to SPASM.

 

the car is flatter and faster no doubt. It feels unnatural, however.

 

I would only ad PDCC to my 991 if it came with airsuspension ;-)

 

As a PDCC SPASM owner, I call bullsheisse, although no personal offense intended to the author, who is a good man. The 991 PDCC is not the same as an SUV in performance dynamics nor does it have the programmed parameters. Sorry but if you don't have PDCC (and haven't driven with it for a few months) it's likely you won't be able to give interested drivers the right info. SPASM will give you added stiffness but PDCC is programmed to adapt to your driven style, including when your aggressiveness to the curves changes. I have felt it on the Blue Ridge Parkway.

If you love driving on twisty roads, PDCC is for you, speaking as someone, who wore out his PASM shocks in his 997. if you love carrying groceries in a status symbol, the SUV is for you and the SUV PDCC will be tuned for that lifestyle, i.e. keeping your GMO food baby from jumping around, not keeping your sports car firmly planted on a twisty, mountain road or race track.

 

I read somewhere that the driver that did the 7:37.8 or whatever at Nurburgring was praising the PDCC for what it did for the handling. I have a Cab so can't have SPASM but did some very spirited driving yesterday in NW Washington and I was thrilled with the handling of the Cab under some severe cornering pressure (so to speak).

Also, somewhere on either 6 Speed or Rennlist that PDCC is being credited for reducing tire wear because it keeps more of the tread on the ground when corning.

 

I drove a Cab the other day and for the first time since I've been driving Porsches (45 years) I was pleasantly surprised to find it stiff enough. I'm not sure the track guys would pick it, but for general spirited cornering, it's great.

I was simply talking from an "on the track" perspective. That is probably why Porsche didn't even offer PDCC as an option for the GT3. I dont know what Frank69's intended use for his car. I don't use my Porsche for parkways, I track it and appreciate its heritage.

 

PDCC is a great choice, I have tracked my car several weekends now and it is amazing how fast and flat it will take the curves. The feeling with the car is exactly as real as it was with my 997tt, and on another positive note, the tire wear is much more even with PDCC.
