My new-to-me 911_50 (enroute to me) has PDCC. If I'm not tracking the car, do I care? For those that have it, do you notice it when driving on the street? When starting the car, is it on or off by default?

TIA

i keep mine on permanently!

I have it. Seems to work well. it is ALWAYS on. When you press the PDCC button it just puts it into sport mode. They are essentially hydraulic sway bars. So smoother over bumps but the body won't lean into turns.

I was surprised how noticeable it is. I drove a TT without PDCC until I got mine with PDCC and the ride is much better with PDCC on. I just leave it on all the time.

No need for PDCC for normal street. Also, I heard someone had it failed during autocross with high Gs.

For me, I'll go with brake upgrade. I'm sick of having to look at the rust every time the car is washed and having to polished it with rust remover (yes I know driving it will remove it).

10 grand just to not see the billionth of a millimeter of superficial rust on rotors that disappear anyway after 10 seconds of driving?

you need to track a PCCB car ... 3 days on the Ring convinced me of their worth

Interesting article in porsche club magazine about carbon ceramic brakes. Useful info that I did not realize.

Well, that's a good point. But PCCBs offer more than just absence of rust on the rotors:
1) There is absolutely no brake dust, none; the brakes and the entire wheels look completely pristine like *Always*
2) The disks are bigger and to my eye look so much better on the car especially if you have 20" wheels
3) Of course, they perform better
4) If you don't track, you will likely never need to change them for the life of the car
5) Wheels are a very prominent part of the car. Why not spend 5% to 10% more to get the benefits? The higher the base price of your P-car, the more it makes rational sense

If I were doing a custom build I'd get them.

Divide the hours upon hours of extra wheel cleaning and they will pay themselves off!!

I spend just an extra hour per wash just for the dust!

Getting back to the OP. There seems to be a misunderstanding about PDCC. If you have PDCC it is always on. PDCC means you have the hydraulic sway bars. When you press the PDCC button that DOES NOT turn PDCC on because as I said it is always on. When you press the PDCC button it engages sport mode. The dash will say sport mode. So on the street I don't press the button because sport mode js a little harsh.

If you have crappy residential streets and own more than one sports car, you will realize the PDCC car is smoother on rough roads than your other car(s).

Just to be clear, pressing the button (w/ the shock & PDCC on it) puts you in "Sport Chassis" mode (stiffer) instead of "Normal Chassis" mode. Not to be confused with the "Sport" mode you get when you press the Sport button. At least that distinction exists in my 991.

I think the former suspension button w/o the PDCC inscription made more sense. Since there is no PDCC "off", it is a bit confusing to have the button labeled in that way, IMHO.

Separately, I understand and appreciate both the pro and con arguments for PDCC. No right or wrong, but preference.

But to say it is only "needed" on track and/or pointless on the street is oversimplifying. It can be very helpful on bad roads, primarily by reducing copy effect transmitted from one wheel to the other via a beefy rollbar. Not only increasing comfort, but also helping with grip.
