Any body out there with experience with the PSS9 kit from Bilstein???. I know they list the kit as F4-GM5-C189-H0 (non PASM) But can somebody give their impressions.? Did you still install anti roll bars (sway bars)?? How did you find set up/best ride height. or is there another kit that’s better, KW???....Help Please before I buy the wrong thing !!
PASM - Porsche Active Suspension Management
This active damping system offers continuous adjustment of individual damping forces based on current road conditions and driving style.
The driver can choose from two setup modes, ‘Normal’ and ‘Sport’, using a separate ‘damper’ button on the center console. ‘Normal’ mode is designed for general road driving and circuits with uneven tarmac. ‘Sport’ mode is intended for smoother track surfaces, where the harder settings help eliminate pitch and roll.
In either mode, PASM continuously evaluates the current conditions while automatically selecting the corresponding damper rates from the respective set of mapped values.
A range of sensors are used to monitor the movement of the body under acceleration, braking and cornering maneuvers, as well as on poor road surfaces. The PASM control unit then evaluates this data and modifies the damping force on each individual wheel in accordance with the selected mode. The result is a significant reduction in body movement as well as a better grip on the road.
For example: if ‘Sport’ mode is selected, the suspension is automatically set to a harder damper rating. If the quality of the track surface falls below a certain threshold, the system immediately changes to a softer rating within the ‘Sport’ setup range. When the quality of the tarmac improves once more, PASM automatically returns to the original, harder rating.

You are Thinking about buying the wrong Expensive thing

Terry, and I run on Eibach CAyman S Sports Spring Kits (you already have the part numbers from previous enquiry) to be honest it is all you will need at a reasonable price, together with the H&R Solid Sway Bars.... PS9's seem expensive and high maintenance to set up etc.....
(Thought you posted recently that you already did your suspension....?)
Oh! That was the GT Sticker.......... There are still only 2 in the UK then....

Hi, I put in the pss9 and the H&R Sway bars ( as well as a front strut brace ).
I Love it! the car is more smooth all around, bumps are less harsh, they respond faster then the stock shocks, the rattles the car had went away.
When changing lanes in traffic really fast, there is a Lot less body roll and the car stays relatively flat.. it is a nice feeling..
Soon it will be auto crossed and tracked ( end of next month )...
Setting is #4 on the pss9 for road.
We lowered it 1 inch, and it was perfect, then 2 weeks later we where dragging on everything as the shocks settled. We had to go back in and have it all raised 1cmm and now it is perfect, no more dragging on speed bumps or our driveway....
kareldeeley is correct, after the install you have to have the car cornered and aligned...... Well worth the hassle, and easy to adjust once installed and setup.
Regards
David

if you are going for adj suspension, go for cross or motons or jrz. don't waste your money going for something that is not that much better than the springs mentioned above. I made that mistake on my audi, I got h&r adj suspension and immediately outgrew them and went to double adj stassis motorsports suspension. what a waste of money that was. Either go all the way or don't. Pss9's are really not up to snuff. Any racer will tell you pss9's are ****. I'm sure those of you that have them will disagree but once you go to moton's or something close you will agree with me. On my boxster race car I have JRZ. If this is always going to be a street car just go with springs. Just my opinion.
PSS9s are just an affordable compromise between street and race suspension. You would not want a race setup on a street driven car, and such setup is few grand.
PSS9s can not be compared to a real race suspension, their adjuster is greatly unreliable, and definitely not linear and does not have 9 steps. All you get is 9 numbers on a dial, but they do not do what most people assume.
At the same time they are good shocks, with nice linear springs and height adjustability. Shocks are also matched to the springs - which is great.

PSS9's may be cheaper than Motons or JRZs, the cost is similar to the Cross system. Where the PSS9's are a set system (you get what they have for your car) the Cross system you can customize the springs based on what your intended usage is. You can order lighter springs, if the car is going to be used more on the street than on track or heavier springs if your primary use is tracking it. Cost of the Cross system is close to the PSS9, but the Cross system comes with adjustable camber plates, where the PSS9s do not have them. Also, ride height adjustments are much easier on the Cross system.

Thanks for all your help guys. I actually have the Eibach Springs and H&R roll bars sat waiting to be fitted. And was wondering will the Bilstein kit give me much if any more? As I’m from a rally background I will at some point this summer help to develop a four way damping system with a friend who is Proflex in the UK, but that will end up at £1300 per comer rather than £1300 for the full Bilstein kit. It’s probably the age old problem that I want something good for the track, but I also want to be able to use the car “on the road” without losing all my teeth.!!!! And it needs to have adjusters 1) that work and 2) that actually mean something.
Are all the responses, except the 1, are from people who don't have PSS9? I don't either. I have friend who has them on a 996. better ride & handling than stock, zero noise (stock top mounts). zero maintenance so far, 3years after install. They are really nice for street use, and OK for occasional track use. Unless you are really serious about tracking something like motons/jrz/penske is huge overkill and much more expensive. lowering springs are OK but usually wear the stock shocks out faster are just as much labor to install & alignment (corner weighting is not essential & rarely done) so why not change the struts while you have them out. Yes the adjusters are not completly linear but you can definitely feel the differance between the softer/ harder settings. All that being said I got JIC because my car is not a DD & I track & autoX a lot.
