You know, sometimes I wish I would have kept that setup just for the pure simplicity. I occasionally find myself focusing more on adjusting the shocks rather than on my driving. I just can't stop turning those little ***** for some reason.

Tracked my 993 for three years many moons ago, and I found that I just got tired (lazy ? ) of adjusting the shocks back and forth from street to track (already had to do brakes, wheels, harnesses, etc...). So I eventually went with 4 rear/5 front on my PSS9s and left them there. This gave me excellent body control without beating me up on my daily commute. Since the PSS10s have better dials and detents than the 9s, you may wish not mind going back and forth from track to street settings. But may I suggest that you think about leaving it at one setting once you find one that offers you good balance, then work on your driving input from there. When you find that your car is balanced and appropriately responsive, it is you that can initiate under or oversteer with simple/minor driver input. FWIW, once I found a setting that worked, focusing on my driving yielded better results than futsing with yet another setting. Again, just my experience ...YMMV.

I want to thank all of you. I will be at the track this weekend. I'll be driving and evaluating various set-ups, Yes, one thing at a time.

Answers to some questions.
Fikse wheels with 245 and 275 Hoosers. About -2 degrees camber both front and rear. Car has been lowered to RS height.

I felt some under steer last time at the track, but was trying to figure tire pressure.

I'll will let you know what I came up with.

Again, Thanx.

Listen to the winners.. Mark is (too modest) consistent and fast. Send $10 to IWANTTOBEFASTER.COM and donate to NIGERIANSCAMS.COM if you like also.. Or ask all the other guys in 993's that are kicking ***...

You absolutely cannot generalize sway bar settings for the 993. What works for one car is dangerously loose on another car. All you can do is start with something sensible then adjust for your car. E.g. on a fast sweeper, does it feel unstable/loose?

Also, (not sure for PSS10) but on PSS9's the "1" and "9" are a fair step from the adjacent setting (ie. 2 and 8 respectively). The changes between 2 and 8 are finer. So if you go from "3" to "2"...don't expect a similar small change going to "1"...its a big change.

What I have GENERALLY seen...and I emphasize "generally"...is that the sway bars will need to be a little looser on the back than the front relatively speaking. They are not the same...so be careful how that is interpreted.

What I did, to get the feel early on, was run the front and back at mid range on the shocks, and then switch to 1 on the front and 7 on the rear...and then switch to the opposite (front and back) to get a sense at how the car responds. I don't go to "9" because the springs become under damped and that is a whole different feeling....at least for me.

For DE's, leave yourself with understeer...your wallet will probably thank you in the long run.

I think you're better off going fairly stiff, like 2/2 or 3/3 and seeing whether one end of the car or the other hops. If so its set too stiff. A 1/7 setting would be very difficult to drive on the track. The struts were made for the car, it makes sense that the lower settings are for track use. I have never used my PSS9 on either end set softer than 5, even on the street. Once you get rid of the hopping a click or two front or rear is going to balance it out, along with the sway bars.

If anyone tells you there is a general setting or guideline on a 993 they are full of $hit. You will need to get someone to help you set up the car to your driving style. Asking for general setting here will waste your time. Sorry to be blunt, just the truth.

I have been trying to get my 993 set up for years, different tracks, different environments, different springs, different shocks, different sway bars, double adjustable, triple adjustable, different tires, different tire compounds, differnet alignments (camber mostly), it is complex. I have been successful but only testing in my car. Other 993's are vastly different even from the same year and timeframe.

Good luck and enjoy the ride....I have enjoyed tickering with the car immensely!

I was in the same boat as the OP when I got mine. No clue where to start. So what did I do, I asked everyone I could find with a 993 and PSS9's what they did...saw a bias towards three things and then started from there. What I saw was PSS9 settings on the track will tend to be the lower end of the range (which makes some sense). The rear end tended to be a "higher" number and the sways tend to be looser in the back (when using PSS9's). Some where opposite, yes! But I certainly did not find a completely random answer when talking about PSS9's and adjustable sways. So that is where I started. If anything it should be safer than coming at it cold in the opposite direction. Once I got use to it, I futzed around with some wild swings in the other direction and discovered the dynanmics that came into play. For someone new at the time it was a great experiment (and it was drivable!!) No doubt that some would do the same and like what they find!! Frankly until I hit 100 DE's I am not sure I can sense the difference between a 2 and a 3...or 4 for that matter. I do feel a difference between a 1 and a 2!!

If someone is setting up a car to the level that you are and can drive to the limit, then I agree 1000% with the statements. I did not get the sense that the OP was there (I sure am not!!).

I come from the opposite end of the spectrum........just go drive it. The only adjustment to the yellow car since Steve set it up for Kim was Tony Colicchio turning the shock **** on one end 2 clicks (Moton clubsports). I figure if I can stay ahead of any GT3RS, etc. and flirt with 2:00 flat at Thunderhill on the full track, all is pretty good.

On the C4S, when I put the PSS9's on and had Kraus do a plain street alignment, I threw some 6 year old Hoosiers on for a Laguna day and turned the settings to 9. No complaints. At least until the brake pedal went to the floor.......

kary993

Exactly, no one here using PSS9's or 10's that are driving at maximum, specially with stock cars as has been mentioned here. You made the point very well. Set it stiff and drive, when you can tell the difference then I suggest you purchase other components and make set up adjustments, until then full stiff on track, soft on street. Done

DaveM993

I resemble that remark

jsh

Looks like this thread is dead, but one clarification....the settings on the PSS9 & PSS10 are different. Stiff on the PSS9 is 1, but on the PSS10 it's 10. Who knows why Bilstein did this, but it's a little confusing if you're used to the 9's...

I don't have experience with the PSS9s or 10s on my 993, but I had a Boxster with the PSS9s and did spend some time setting them up. My recommendation is to just set the shocks to full stiff front and rear to start with. They are relatively soft shocks for the track so you will always want one end or the other on full stiff, and it is just a matter of finding out which end you need to dial back a bit, if any. Put the sway bars in the middle setting front and rear. Then adjust from there based on how it feels.

I would personally start with adjusting the shocks rather than the sway bars in making adjustments, but that is a matter of personal preference. From the initial max stiff setting, soften the shocks on whichever end of the car feels as though it isn't getting enough grip.
