Lowering a 997/997s is a perfect example of the law of unintended consequences.
Benefits:
-Improved appearance
-Reduced body lean
-Improved handling
-Desirable for a car that is frequently tracked.
Drawbacks:
-Frequent grounding of front of car on normal driving
-Can't pass over a speed bump or driveway
-Harsh to bone jarring ride
-Interference of tires with bodywork
-Premature failure of stock shocks
-Alignment problems from high negative camber
Be careful what you do, you can screw up a $100K car for $2K.

Some people here are making way to much of this. It's clearly installation related. Many driving around with lowering springs and no issues.

Hartly, I am certain that it is a problem with the installation

The best way I've been told to lower the car and keep the PASM is to switch to Bilstein PSS9 coilover system that supports PASM (electronic) or "Damptronic".
Or, full non-PASM coilovers as regular PSS9 or Cross coilovers.
Although many have had thier car lowered with H&R springs or other mfg springs, you can always run a risk of overworking a shock, and if electronic, the computer sometimes gets confused and can actually increase the failure as it tries to react as the springs work in a shorter travel than it's original design.
No one has ever recorded shock failure due to "lowering springs" as far as I know.
Also, some insurance companies are getting very aggresive in accident investigation to body damage that may be due in part that the car was lowered. More so if the engine took a hit from a rear-end collision to the Porsche. If they find the car was lowered and by having it lowered also contribute to damage that they find, they can deny a claim.

I am well aware that there are risks to lowering the vehicle
I have had other vehicles lowered in the past without failure. I think that the hardest thing to understand is how it would fail without moving the car. The springs were installed and the problem occured. No actual miles were put on the car after it was lowered. I have the car back to stock height and the failed shocks are in the sport (firm) mode (as Porsche designed them to do so).
I am aware of the Bilsteen and will probably look at them in the future, but I think right now I just want the car back to working condition.

My problems started at 9K with a PASM fault that turned sport mode off during a road trip to Vegas. Had to stop and restart the engine before I could get sport mode back. The PASM fault was thrown because the shock bottomed out.
