As many have mentioned, the 'PDCC' printed on the suspension control button is extremely misleading. The system is always 'on' with level of engagement controlled by the computer, along with PASM shocks, active engine mounts, etc.

The PASM Sport button has PDCC on it to seemingly only to tell drivers they have the PDCC system (along with all the other active suspension features). Engaging the stiffer, more aggressive 'sport' mode affects all of the systems just putting them in a more aggressive mode.

I have PDCC on my 991 Turbo S and often drive it back-to-back with my completely analog but completely dialed in 996 Turbo. I've never felt like the PDCC was overly intrusive or overly artificial on fast canyons or the track, though I also run a DSC Sport + controller which takes these active systems to the next level.

PDCC is only a 'comfort' thing in the sense that it allows much more roll stiffness than would be acceptable on a 'grand touring' street car without the active management. Stiffer roll stiffness when you need it, softer roll stiffness when you don't.

Having PDCC would never be a deal breaker for me and absolutely not a reason (IMHO) to miss out on an S vs. a regular Turbo.

Exact reason why it may be a deal killer.

My next 911, a custom ordered 911 Turbo S, will have PDCC or I'm not buying it. I'm tired of leaners!

Hi All,

I have a question, which comes after reading the Autocar Turbo S review (here: https://www.autocar.co.uk/car-review...he/911-turbo-s) in the UK.

In the review they voice a real concern with daily driver road handling, and in the first few paragraphs of the write up they mention the car is optioned with the -10mm suspension package. I'm looking at a spec on a Turbo S and wanted to know if anyone has any experience with this on a 992 TTS? Does it significantly change the character of the standard suspension?

Thanks

I had a 992 Turbo S with -10mm SPASM and I found the car to be pretty harsh on rough surfaces. Just taken delivery of 992 GT3 and to me the suspension feels way more compliant! Go figure…..
I think tyre pressures also play a part.

That said, I’d have another Turbo S in a heartbeat but would skip the 10mm SPASM

Thank you Edmac - great to hear and much appreciated.

Ride quality and handling are excellent in all modes in my 992TTS with SPASM and PDCC.

Try it first. The "unnatural feeling" is way overblown, IMO. It just acts like a much stiffer suspension but without a corresponding penalty in comfort or traction. The car still leans, just much less, comparable to the last GT3 RS and more than most real race cars - nothing unnatural about that. On 911s, PDCC does not even do that much, especially in cars with SPASM because lean is minimal already, and that's why I do not think it's a "must have", but definitely not a detriment. It may feel unusual at first to someone who is used to cars leaning, similarly to how replacing old out-of-tune speakers with a new perfectly sounding set sounds all kinds of wrong for the first week or so. But once you get used to it, it's the other way around. After driving only 911 Turbo S with PDCC, Cayenne with PDCC, GT3 RS (almost no roll without PDCC), and Radical race car (no roll naturally) for the last few years, when I jump into my dad's BMW 5-series, it feels like it's about to roll over, and I feel annoyed waiting until the car finally takes a set so that I can proceed with the next control input.

For me it's a must have. Great looks with SPASM 10 mm lowering, absolutely flat cornering, and comfort or Sport setting. I'm not buying one without it!

Do you use comfort tire pressures? That made all the difference for me.

I have both -10mm SPASM and PDCC and can tame the ride if I want by driving in normal settings. But it will firm up in sport as it should. Went for 4 hours drives and in normal/comfort chassis settings felt more than compliant.

I would say the same. IMO the SPASM is a must since the TTS stance is a 1/4 higher than the base 992 S. I think it looks better for us aficionados.

Edmac

I didn't use comfort tire pressures - maybe should have. I'll try that on the next one

The standard pressures on a 911 (max load, max speed) are ridiculously high on all gen Turbos and pretty much ruin the ride quality and handling, PASM or SPASM.
