So the only question left, is: are you off your medication, or are you just trying to game the system to cause trouble? In either case, I think you need to rethink your behavior.
I think a public apology is in order for both playing with yourself and attacking others. Playing with yourself is something best done in private, rather than sharing it with the rest of us. Do it again, and you'll be banned from these forums.

You must say 100 Hail Marys, apologize to Rennlist, and deliver yourself to confession before you go blind.

I think that we shouldn't have to hear about playing with oneself and also we shouldn't have to hear that jumping up and down on one corner of the car is a good test of the shocks!!!!!
That technique worked for american cars from the 1940s till somewhat more recently...it doesn't work for 993s or other performance cars.
Arg!!!! This thread is hysterical!!!!!

What kind of deals does AJUSA have right now... I could only find $2289 for PSS9s which is cheaper than Carnewal's exchange-adjusted price... anything else I'm missing?

shocks and things

My point is that unless we have some basis on which to compare the system at hand to one that is "perfect", we're likely to miss the fact that the shocks are worn until they get really bad and start pogo-ing down the road.

One individual - posting under two different names? It's hard to believe the lengths people go to sometimes. Arent there better things to do with your time? This board is a great source of porsche info and opinions. Dont flood it with crap please... (but it's funny when you get caught!)

1. I also waited too long - changed at 72K.
2. The static push down on the bumper does not reveal the problem.
3. What did reveal the problem:
a. pogo effect in high speed sweepers, like cornering on Jell-O
b. straight line harshness over bumps
c. repeated cupping of even new tires (starting at 45K), even on a fresh alignment.
4. After-market Bilstein HD have about 45K on them and feel like new.

BUT, if you think you have the right tuning for your car, it is not going to stay with you for very long (again, I bet less than 5,000 miles).
The other thing that seems misunderstood is the role of gas in a shock. It is not there primarily for tuning with pressure - it is there to keep the oil from cavitating. Since the shaft run inside the oil, as the shock compresses, the shaft displaces oil. On rebound, that creates a vacuum and the oil will cavitate - completely screwing up the damping curve. With Nirogen gas, there is pressure and compressibility which kills the cavitation. A shock only needs a small amount of pressure (5-10psi) to accomplish this task. Tuning with gas pressure is a secondary function and many experts feel that is a band-aid for improper shock tuning.
Mechanical wear is a different matter. Shocks can last a long, long time in that regard, but the damping will not be the same. If you are serious about your shocks, you will replace the oil on a regular basis and have them rebuilt regualarly as well. Most people can not feel the difference between significant shock changes but a shock dyno will show the reality.

Thanks for the explanation Mark. Actually, despite the self gratification parts, one actually walks away with a little knowledge and some take home opinions from this thread. Bravo for bringing it back on point!
