Bilstein PSS9 (B5 S4) dyno results, and suspension ramblings.

each colored line represents a different shock setting. the grouping of lines & the
separate line show that the shock is working almost exactly the same for all but one setting.
the single line with a very different path is the "other" setting of the 9 options. the remaining 8 are following the same trend-line. actually one line may be deviating, but it's pretty much going to feel the same.

Re: so will stiffer springs be better suited to the PSS9 in your opion? :-)
I think PSS9s have enough rebound to accept a stiffer spring, you could add about 100 lbs without issues. If you crank up to stiff, you could add 200 lbs or more. The problem is that stiffer springs require softer compression settings. Bilsteins add compression at the stiff setting. I do not understand that at all...

Absolutely. Steve at Bilstein is happy to revalve the PSS9 kits. More than one customer...
actually keeps one set at BS USA and one set on the car and communicates track results over the phone with Steve as he sets up their valving and ships out the set to them. He has been helpful to me in the respect before. There is a cost for the revalve though. As for spring rates. Bilstein reports the setup is good for 650lb springs with no need for a revalve at all, perhaps more but they are not willing to commit.
