Good stuff, I have no 996 experience, but in total agreement with your take of the other two.
That 991S drive train and suspension is really fast, yet supple. Superb DD.

Great writeup, and even better videos.
PASM (Porsche Active Suspension Management) - Two stage, normal and sport
PSM (Porsche Stability Management) - 2007/2008 GT3's do not have PSM. They have TC, and it can be completely turned off.

Hesitant to post, but I believe the "switch" for PASM in the 997.1s is for Sport mode on or off... When off, PASM is in "normal" mode and still engaged.
I did find the following post from Vivid Racing through a Google search... It addresses disconnecting the PASM controller to enable after-market suspension...
Porsche PASM Delete Instructions
Installing aftermarket shocks or coilovers on PASM equipped cars will result in fault codes and check engine lights. This procedure will disable the PASM system.
Doing so is done at the owners risk. Vivid Racing assumes no liability. Disabling PASM will revert the car to its stiffest factory shock setting and will disable shock setting switch in cabin. Operating the vehicle in this condition may result in loss of control!
1.) Connect Porsche factory scan tool to car with ignition key on
2.) On main screen, select “Gateway” under the Control Module heading
3.) Select “Coding”
4.) Select “Required Control Unit Lists”
5.) Select “PASM”
6.) Select “Not Installed”
7.) Select F8 key to back out to main screen
8.) Turn off ignition key
9.) Disconnect PASM module (Normally located behind carpeting on right side of passenger footwell)
10.) Connect PIWIS Tester with ignition key on
11.) On main screen, select “Special Functions”
12.) Select “Vehicle Handover” and follow directions
13.) Select “Functions Complete”
14.) Select chassis number
15.) Select F7 key
16.) Back out to main screen and select “continue” under Control Module heading
17.) Clear fault codes as necessary from any DMEs

I know we have covered this on numerous other threads.... I agree with Dell that it has been established that PASM can't be turned off fully on the 997.1 gt3. This was an issue discussed ad naseum on Rennlist in 2006/2007 when the 997.1 GT3 came out... I am not sure if anything was changed on the 997.2 however, so will let you guys chime in...
I wrongly assumed it softened and stiffened the shocks only to be either permanently one kind of softer or the other setting one kind of harder.
I did not know that adjustments were active in either setting.
I never felt anything adjusting bouncing around in the softer off setting in the GT3, but tried setting it soft before T17 and harder after T1. The .2RS needs always harder setting.
Nothing posted after 2008 I guess or there were probably too many words inthe PASM threads. Luckily there's youtube

What issue?
I love PASM, also in the .1.
But my *** is probably not sensitive enough to feel it being active on track.
Not driving on track, if I forget to push the button back to soft, I'm annoyed by the harder ride before I get to the gas pump..
Anyhoo, did anyone feel the 991 Torque vectoring yet??

You're correct Dell, PASM does NOT have an off switch in the 997.1. Some think the mini shock absorber button when not illuminated means i'ts off. Not the case at all; this simply means its in Normal mode. That mode is designed for circuit driving, irregular roadways etc. When lit, you are in "sport mode" with a stiff suspension, speedway I presume. It would be an interesting experiment to see how certain corners are received by the car's suspension in the two different modes. Guess I'll have to test that one at FSR on T4..... :-)

Good point, and I now understand why the 7.2 GT3 crew is so amped on the car...
I just spent the last hour "searching" my *** off (Google, 6speed, Pelican, Pistonhead, Rennlist)... I keep coming across TRAKCAR posts!
Anyway, learned a lot about PASM, PSM, TC - and several other acronyms from a Larry Cable post on 2007:
*ABD (Active Brake Diffirential)
*EDC (Engine Drag Control)
*ASR (Acceleration-Slip-Regulation)
Damn - lots to learn about....

I recently heard someone at the dealership say that if they tuned Porsches to go over a certain Torque # in certain gears the ecu automatically dials it back.
They run into it often with TT's, but apearently also with GT3's?!
