Dividing the 10 settings into three groupings...
Low third range works for the street comfortably

Middle third range is aggressive for the street and may be suitable for some track

High third range is likely track only

....my guess

#5 F&R last I checked. I am satisfied with the ride and performance and never fuss with the dampener settings. The ride is firm but precise.

Jay,

Are sure that you don't have it backwards ? 1 is the stiffest setting and 10 is the softest. I run mine for the at R=6 , F=7.

JD I was okay putting that out there because I knew you would catch me :)
Just thinking out loud and putting some logic out there.

Just make sure you are aware of your settings before you hit the track....the softest setting may give you a problem

Too much Viagra ? :)

Yeah my dampers are on 11.....er ehmm -1
...did it again

I run "9" front/rear (full soft) on the street and "1" front/"3" rear on the track. I adjust them back and forth regularly.

Topless likes a more compliant suspension than I do so and we both run fairly similar lap times, hence there is no "right" or "wrong" here, just remember to adjust for your particular driving style.

I run "9" front/rear (full soft) on the street and "1" front/"2-3" rear on the track. I adjust them back and forth regularly.

Topless likes a more compliant suspension than I do. I like the front as precise as possible but add a little more compliance to the rear to keep the rear tires planted on corner exits. We both run fairly similar lap times so there is no "right" or "wrong" here; remember to adjust for your particular handling preferences and driving style.

As I said, I run mine at 6 in the rear and 7 in the front for street. I'd love to know what spring rates were selected when my PSS9's were built ? If I were to dial them to a lower setting, I'd have to increase my dental insurance.

Do you have the standard blue Bilstein springs that come with the PSS9's or an aftermarket spring?

9ff selected the spring rates based on the type of driving the car would be used for. I trust that they made the right choice. However, it seems impossible to imagine that my vehicle could be driven on settings that fell below 5. But, then again, I have never tracked my vehicle either.

Remember that spring rate of the tires is part of the equation. A 19" might have an 80% higher effective tire spring rate than a 17" tire. If I were JD running 19s on the street I would probably always be set full soft PSS9 dampening.

Okay did any set up on spacers or is this a big no no?

I really like my 15s up front give me a more stable steering front end

I have 23s at the back that may not make it.

So do I set up spacerless and space out later:rolleyes:

Not sure I will need them if the ride height and cambers will have me all tucked in (JD this is not intended as an opening for you)

Anyone? This will affect wheel rate as there is larger moment on the arms.... Effectively softening the springs a touch.

The spacers will screw up the alignment I am told.

Putting them back on after will also change the track, maybe effective contact patch, corner balance....yes?

Talking about using wheel spacers for a wider track? It will change suspension marginally but probably not enough to notice. I would run the car first without, as long as the wheels fit. Add spacers after you have a good baseline on your setup and compare results.

Yes in theory but not in my experience. I use small spacers on my street wheel set to avoid any rubbing on the PSS9 rear shock because they are 996 rear wheels and are 1/2" wider than the 986 stock rear wheels that I use for the track. I can't tell any difference between having the spacers or not.

Agreed, you'll never notice any of those minor affects from spacers for any combination that still fits in the wheelwells.
