PSS9's are excellent. Not hard to adjust at all. After some practice, one can do it without looking or jacking the car up.
Be mindful though that some clubs will add 'points' or even bump you to the next class with PSS9's as they are considered adjustable suspension (which they are).

After a great deal of research, including a long talk with Gert at Carnewal, I had decided to go with X74 (but I traded the car before installing). It really depends upon your needs, but unless you truly need adjustability, do yourself a favor and check out X74 carefully before you make a decision.

FWIW, I had the RoW M030 on my C2. A couple of observations:
1.) I was only able to get about a degree of neg. camber up front with this suspension. I assume since the PSS9s can be lowered, you can get more camber? (TD, is that true?)
2.) On the roads around here, I found the M030 to be a harsher ride than a friends' PSS9s. In fact, the RoW M030 is actually a little harsher on certain roads I know than the GT3 is.
3.) The sways on the M030 are stiffer than the stock ones, but not as stiff (or adjustable) as the GT3 sways (which can be installed on other 996s). TD, correct me if I'm wrong, but you do have the GT3 sways, right? Personally I think those do a lot for the poise of the car on track. Certainly being able to fine tune with the sways is nice.
4.) The PSS9s do allow you to corner balance your car. Don't know if that's a big deal, because my last car couldn't be balanced, and my present car was balanced before I took it to the track. So I honestly don't know.
If I were doing it again on the C2, I would def go for the GT3 sways, and probably the PSS9s if not the new, less expensive, integrated JRZ units. Which I think are pretty compelling and are a definite cut above the PSS9s.
Anyway, FWIW.

In all seriousness adjustments are a pain and 90% of guys leave them set one way, so why bother?
I'm a simple country boy and like one less variable to have to mess with at the track.
Just do the RoW030/X74/X73 route, you'll handle great, be plenty low, preserve your warranty and have all the factory RD behind your decision. They really put alot into suspension designs that I think tuners, with off the shelf coil overs/ one size fits all, just can't match.
I wonder, how many pss9 guys really adjust their suspensions , and how often? Not many and very rarely I bet.
Ask Yetis how he likes his, or Ken.

RoW 030, half the price. Then again, what do the porsche engineers know? Unless you go to multiple different tracks, pss9's are a waste of time IMO, 90% of the guys who have 'em, don't really need 'em, if they do they otta have Motons anyway. JMO guys, adjust away if you want, just be sure and give me an early pass signal at the track.

I have the JIC's on my car right now. If it were a weekend/track car, they would stay. However, with a recent job change, I now have a 45-55 minute commute on what could quite possible be the worst roads in North America and they are killing me.
On the track it was amazing, the car was so planted, stable and jut a joy to drive with the coil overs and GT3 sways. So, I cannot say enough about the abilities of the JIC's and their ability on the track.
Moving to the road, it’s a bit of different story. The ride can be very harsh, and definitely will not win you any awards with the other sex. It was fine for the weekend but everyday has proved too much. I have had 4 alignments in the last 5 months. I should mention that I have put 15K miles on the car in the last couple months. You can corner balance, but as a novice tracker and without a garage, I have not adjusted the height once. I have adjusted the rebound/compression, but that only goes so far in terms of ride quality.
I notice the original post is from someone in California. I would say that location will make a huge difference as the roads are in better shape and there is no corrosion to the suspension in the winter or height adjustments required.
I am going to move to ROW30 as I want something that I can leave on the car if and when I sell it.

If you never track your car, playing with the ***** is not that big a deal on the street. Whenever you change the ride ht, you need to check the alignment, now that's a pain . Significant changes in ride ht will induce bumpsteer during high speed cornering if not done just right.
I think you're probably in the minority, as most guys never adjust their suspension with those setups IMO.

You can change the settings without alignment!
