To PDCC or not to PDCC that is the question?

Lol, yeah, that does look like we are within a couple of feet of the same spot in our avitar. Look closely at the location of the metal grate relative to the roof of the car? Any chance you just took a viper out of 5 on the way to 6? Maybe just cropped it out of the pic?
A friend of mine got an estimate of $20k to replace his PCCB rotors from his dealer. This was after 2-3 track days and something like 15k to 20k total miles. If they do last for the life of the car if not used on the track, they might be worth it. But I was surprised how quickly they wore out on the track, although he does like to be one of the last of the late brakers.

Agreed. I love it. Amazing on crappy CA highways, mountain roads, and even better on the track. The feeling of 0 body roll is amazing. If you're in a GT3 now, without PDCC the car will feel super soft on corners without it.

I guess I am going to have to test with & without to really decide ...

Larry,
I am on the fence with this option also. There isn't a ton of info on it, and right when you read a couple of opinions stating its not worth it, you then stumble upon a glowing review saying its a must have. We both drove GT3's, so I think the PDCC option would be a nice compliment for us, since we are used to the stiff suspension of the 997.2. When I test drove the 991S without PDCC, my first thought was, "holy crap, this thing is rocks back and forth like a boat"

I'd be very surprised if the PDCC swings in firmness are as varied as above. First I think the parameters are limited by sport / sport plus selection, then further narrowed by how the car is driven at the moment. That is to say that if you are in sport plus on track driving hard, I don't think you have a soft rollbar on turn-in. Some adjustment might take place (and probably does with the however many readings a second), but I do not believe the car swings from soft to hard and back, but rather stays at the firmer end of the spectrum with minor modulation until you alter modes and/or selections.

Missed that point on your first post in my hast to help. I would have liked the SPASM but wanted a cab too.You must have the Tire Rack on speed dial.
I'm pretty sure some Rennlister's have reported such, and I'm almost certain I read this last year in the Porsche sales brochure. Regardless, your wear sounds pretty even considering your use parameters.

I guess I am going to have to test one with and one without...

Makes perfect sense to me that some people don't like the 'delay', and there must be one. Car turns, sensors sense that turn and tell ECU, and then ECU reacts and does stuff with PDCC. All that must take some time, even if it's very small. When that first happens the roll bars are likely soft and then harden (tried three times to write that better...) which probably means under-steer before it settles. That said I'm personally not good enough to sense that myself and I find a bigger difference on turn in on my two 991s between 'normal power steering' and 'power steering plus'. The later I'd never spec again!

but then my wife suggested I get rid of the GT3 and replace it with a cabriolet.
now ... I am NOT getting rid of the GT3 ... but
what if we get a cabriolet, with PDK so she can drive it too, and something cheap to take the dogs out in?
that's the plan ... but since this will be my daily driver, its got to have some performance, hence PASM, Sport Chrono, PSM, probably PCCB, because I am
their only fan ...
