Why does the 964/993 Crowd Get PSS9's and We Don't???
Why do these wussie guys get to have all the fun when it comes to new suspension goodies?? 
Don't they know that real Porsche drivers only drive 930's? 
All kidding aside, is there any notion that Bilstein will produce a PSS9 kit for our cars? Is there a comparable ride/performance setup available for our beloved 930's?
I mean, gosh, when you read the descriptions from 993 converts who have gone through ViperBob's installation process, they all sound like they just got lucky or something!

Toby:
As of this writing, Bilstein has no plans to offer a PSS-9 kit for 911's, '69-'89.
Although the Bilstein RSR struts & shocks are economical, they remain early '70's, non-adjustable technology and have poor damping for the vast majority of these cars. These must revalved to work properly someone who really knows what to put in them.
Frankly, there are some EXCELLENT adjustable struts & shocks for 911's and 930's that are far better than the PSS-9's.
You have Moton, Fox, and JRZ to choose from and if they are installed, setup, and correctly adjusted, they add a whole new dimension to what your car's handling and your driving is capable of. The difference is just staggering and Bilstein RSR's or PSS-9's do not even come close,....

Thanks Steve. Ok, so what would you choose? Moton, Fox or JRZ? And what are the pluses and minuses of each. I thinking of a combination street/track (DE) use, so I would like something that does not jar my teeth out on the street, but can give me the kind of stability and adjustment range needed on the track.
What sounds so seductive about the 993-heads and their descriptions of the PSS9 setup is their seeming Jekyl/Hyde nature - smooth, firm ride on the street and planted, flat capability around corners.
What to do, what to do!

Toby,
That has more to do with the original valving. Depending on what you are dong with the setup can dictate what valving you can or will have done, if any. Not one shoe fits all and the nature of some of the setups is quirky on the street and good on the track and vise versa. The coil overs with the raised spindles, revalved if necessary and set with a nice set of bars and if you can stand the noise, a set of monoballs will offer a phenomenal ride over Tbars and very mature planted car. Many run this type of setup in the older chassis and do well. The best part is spring rates are easily changed to your liking and you can find a nice combo between street and track. There are many on the list with these mods. Maybe they will share their real world opinion.

Hi Toby:
What to do?....Here are some suggestions,...
First, your budget & usage split (street/track percentages) really define your choices. As long as you stay away from monoballs, your ride quality will not really suffer as long as torsion bar sizes and shock valving match up.
As Stephen so wisely said, its not a one-size fits all situation and one makes some compromises between street and track use.
That said:
1) Fox single-adjustable, remote reserviour, struts and double-adjustable remote reserviour rear shocks. These have adjustable height spindles and work nicely with torsion bars or coil springs.
2) Moton single or double-adjustable struts and shocks. Doubles have remote reserviours, singles are self-contained. Spindles are custom configured for height and can be offset-bored for more negative camber.
3) JRZ single or double-adjustable struts and shocks. Same options as above.
The difference between these shocks and Bilsteins must be experienced to be believed and will make a 3-6 sec/lap difference, all thing beings equal.
All of these shocks, properly adjusted, ride smoother and are less "jiggly" than Bilsteins, too. You do get what you pay for,...
Lastly, choose carefully who you source these kinds of things through; they must have extensive chassis experience to help you get them installed, setup and adjusted to get what you paid for and be able to service/rebuild them as required.
