Got the new 993 and was thinking of getting the new Bilstein setup. I put my car on the lift and found these. Anyone know how new these are? Do I already have a decent suspension setup?

 

Those look like PSS9s. Someone may have to verify that though

 

That would be my guess as well.

 

I don't see adjusters that the pss9s have. Search the Bilstein site for "HD" shocks.

They are one or the other. And that is good news as you likely don't have to replace them. I personally wouldnt choose HDs for my car, but if it had them I doubt that I would change them.

 

Chad the car looks great with the 996TT hollows! Told 'ya so !

DFWPorsche the adjusters appear to be the black circular dodads that

normally are silver PSS9's or maybe 10's... Bert

 

The previous owner didnt know these were on the car. Handy.

 

These are PSS9 or 10 fronts pictured. 9s have 9 damper settings and 10s have 10. You need to pull the blue cap on the bottom off to make adjustments. The rear adjustments are on top of the shock tower inside the car. They are probably 9s and not 10s because PSS10s came out around 2 years ago if PO did not install these.

Great setup with thicker sway bars. I have them for my 996 and adjust them for track and street driving.

 

I have PSS9's and they are blue. Looks kinda like mine. I'm no expert on this, though.

 

Thanks guys. This is very helpful.

 

I just checked and there are indeed 9 damper settings hidden under the blue cap. Mystery solved. What setting do you guys run on these for normal "spirited" driving?

 

The blue cap rotates - no need to remove for adjustment.
The rears have a visible disc adjuster mounted at the lower end facing the middle of the car. The disc is vertically mounted.

Most find the incremental "adjustment" to be subtle with meaningful change being at 1,2,5,9. Further there is a lot of rotation between 1-2 and 8-9 with tiny rotation between the rest (easy to lose your place!)
Also, after a while it gets hard to feel or hear the "clicks" that help you work out where you are. Note that 1 (hard) is full anti-clockwise, where as 9 (soft) is full clockwise.

Personally, I run 9 front and rear when in road mode which includes "spirited" driving. This is absolutely adequate for handling without ailenating your friends and passengers.
I run 1 rear and 2 front at the track. Much here depends on your alignment, rubber. Go softer at the front if turn in / oversteer issues are of concern. Needing softer at the rear is unlikely as oversteer is usually not too much of an issue with 4WD and sticky rubber trackside.

 

Great tips. Thanks!

 

PSS10 work the exact opposite! 1 = soft 10 = hard

 

I have PSS 10's on mine - what front/ rear numbers do others with this set up (otherwise mine is stock) set them at on the street?

 

Suspension "stiffness" and your tolerance for suspension "stiffness" is so so subjective

On my PSS9, I run 3 front, 1 rear
