big debate that one - their are lovers of the normal suspension and haters of any new fangled electronic thingy stuff. PASM seems to attract very split views
Go drve both make up your own mind.
However for me its PASM every time - I specced my previous Boxster with PSM and it was a complete relevation to the one before. Since then I've been a convert.
I used to do 20-30k business miles a year in my boxsters. PASM and Bi-Xenons were the best two practical options I have ever taken on a car.

Is it not the other way around? The PASM (when switched on) will give a firmer ride, but will adjust itself should the road surface become poor.
I do know that when I switch mine on the ride is more harsh than when off. Typically I will leave mine off, but with the sport throttle switched on.

Obviously a standard feature on the S but cost option otherwise. It is automatically off until you either select Sports mode or press the PASM button. You can even engage Sports and then switch PASM back off.
PASM gives a much harder drive and a better feel at high speeds as you feel more connected with the road. On my S with PASM off - which it automatically is most of the time, I find the drive more than comfortable and I have doen nearly 3,000 miles in 3 months, everyday driving.

PASM is never off - If its specced on your car you have PASM.
Apparently therre are some 7 or more settings that it uses. The system adopts the most appropriate setting for the conditions and how you are driving it. If you go along a straight road at a relaxed pace but don't break into a corner the active suspension will automatically firm up to retain control and give more grip.
In essence your "on/off" switch is telling it you prefer a more or less sporty or agressive set up and picks the settings accordingly. The on button also backs off the traction control a bit to give you more leyway for track work
All porsche suspensions are firm and controlled but I find PASM in normal modes setting is more comfortable than the standard non active suspension over long runds. Others have different views.

Fair enough, I've never driven a non 997 'S' model i.e. without PASM.
Assumed that the button was to turn on or off period.
In any case whichever switch mode it's in - on me S - doesn't cause a problem.

Agree!
My understanding is that the system automatically firms up or softens to adapt to your driving style - Sport mode is generally much firmer than standard, however the softest setting with Sports mode on, is softer than the hardest setting with Sports mode off if that makes sense i..e there is some overlap.
No, my understanding is that the traction control is controlled separately - I have a separate button on the dash for this, but I'm not sure if this is different for Sports Chorno equipped cars? (My car does NOT have Sport chrono).
I find the standard (non-Sport) setting perfect for general use and rarely use the Sports setting except for smooth twisty roads (which are few and far between down here!). I guess this would be most useful for track work.

thanks for the comments - I was tring to keep it simple.
I referred to "normal mode" as opposed to Sport. My error for not clairfying - we both agree normal mode is more comfy on british roads than sport. And as the suspension automatically adapts to driving style its works for me when pressing on on all but the smoothest tarmac. On ultra smooth or track I'd go full sport
In terms of backing off traction control - its tied to the sport button. When on it increases the limit point at which it will intervene - hence backs off as opposed to turns off.
So you can get more out of shape in sport than normal before the TC nanny interfers/saves the day; depending how much trouble one is in. The seperate buttion is to fully turn off TC as opposed to allow higher limits before it intervenes
As to your question I can't remember offhand if its purely PASM related or comes into effect with the sports Chrono.
I went for the tripple whammy Sports Chrono plus, PASM and Sports exhast with the SatNav/entertainment stuff. Apparently this gves you lots of extra features. Not tried any yet
Generally I drive it with PASM set to standard (not sport) but the sport button on for the more agressive throttle response (Chrono) and Sports exhaust. Long motorway hauls I turn the PSE off as well.

I think this is where the difference lies - without Sports Chrono, I don't have a sports button, just a PASM (Porsche Active Suspension Man agement) button and a PSM (Porsche Stability Management - Traction control), and a separate button for the PSE (Porsche Sports Exhaust).
My understanding is that they are totally independent, so switching the suspension from normal to hard has no affect on the traction control and vice versa

Sidekicks - the documentation I have is quite clear pressing the sport button increases the throttles agressiveness, puts pasm into its firmer settings and also raises the limits that PSM intervenes - its designed for track use.
Based on your comments this must therfore be a feature of the combined Sports Chrono and PASM features ie Sports Chrono gives the backing off on PSM. The seperate PASM button allows you to modulate the PASM back to "normal or comfort" while chrono is in sports mode but initally depressing sport button also puts PASM into its frmer settings as well.
You do get a linking of features together when you combine the Chrono and PASM, especially with Chrono plus and PCM where you seem to get some additional features, a ploy to get you to buy more. I just can't remember off the top of my head which bit contributes to which feature.
Either way with PASM and Sports Chrono plus +PCm you get three options on stability management - "Full nanny", "partially nanny" or "its all your own fault". Created between PCM settings and your PASM, PSM and Sports buttons.

Guys we are getting our wires crossed about two seperate functions:PASM:Porsches Active Suspension Management offers electronically controlled dampers allowing continuous adjustment's, automatically adapting according to the road conditions & driving demands. Designed to maximise both ride comfort & handling the system offers two settings, Standard & Sport. If Sport is selected the suspension is set to a harder damper rating, but (as with the Standard setting) PASM can still vary the damper rating's to maximize control, for example improving the tyres contact with the road & improving the ride over poor quality roads, then firming the settings again during hard cornering.
Sport Chrono Package Plus: Adds a chrono dial to the top centre of the dash, this allows you to record your lap/journey times (etc) & is displayed & stored via the PCM module. The pack also includes a sport mode, this changes the cars engine mapping to ensure a far more aggressive response from the engine for each given pedal input. The PSM limits are also set higher to ensure intervention only in very extreme conditions. If PASM is fitted it will also switch the dampers to sport. All this is designed to maximize & focus the cars performance, particularly on track. The system even offers a more aggressive control of the gears in cars fitted with Tiptronic. In addition various memory functions can be stored via the PCM module, including personal preferences for door lock modes, daytime light functions, air con etc.
To confuse matters on the 997GT3 there is one PASM button to make the dampers firmer (like the standard S without sports chrono), with a seperate sport button changing the traction control & opening an exhaust valve for extra mid-range torque (not available on the standard S), so the two functions are split! Whilst a chrono equiped S has one button to fulfill both functions & they can't then be split, e.g you have firmer suspension & a more aggresive engine map or not!!
Spizz.........Bottom line is the PASM offers a more comfortable ride than conventional steels in most circumstances, but as it is adaptive it will firm up when you press on, so could be harsher than a conventionally sprung car when realy driving hard!!

have just bought a 997s 54 plate from opc. will it come with the switchable sports suspension?

I believe all 997 Carrera S models have had PASM as standard. This can be switched to 'Sport' to achieve a harder setting (which will still go softer if the road gets especially bad) but this should not be confused with 'Sports suspension' which can be specified on the Carrera S at no extra cost. This option gives you a permanently firmer suspension, 10mm lower than the standard S, different anti-roll bars and removes the PASM.

ok tks thats interesting. i wonder on that basis i wonder if theres a way in which i can find out if the one i have bought has the "sports suspension" you mention. tks again
