Larry,
I have the Bilstein Euro PSS-9's. They have a single adjustment and quite frankly, I do not know if it is for compression or rebound damping. How sad is that???!!!! Does anyone know?
I have to disagree with your last statement. The perceived relative stiffness (f/r) that is felt will be a function of two things the weight on the spring and the stiffness of the spring (spring constant). You really can't correlate the front and rear stiffnesses unless you have the front corner weights, the rear corner weights, the front spring rates and the rear spring rates.
Needless to say, I have set the front dampers on 1 and will also set the rears on 1 and go for a test drive. Stay tuned for the outcome!!!

 

Well, I set all four corners at setting number 1. I then took the car out for a drive. I drove it at about 6/10's as compared to 8/10's the other day but nonetheless I noticed a marked improvement over my original 3F/2R and trial 7F/2R.

Marked is not a strong enough word actually. The car is handling 100% better than before. So, I guess the valving really wanted to be stiff as hell to match well with the springs!

At this point I do not have anywhere to go outside of changing them out. I would rate the PSS-9 performance, with the current #1 all around settings, at about 80-90% of what I am looking for in a suspension.

All of this experimentation leads me to believe that I really need more of a race suspension. I have a track day scheduled for a week from now and will try this as it is. We shall see how it performs when pushed to 9/10's or so.
