what are YOUR track setting for PSS9

Hi,

I am struggling to find good settings for the track for my PSS9 and was hoping that some of you could post their settings which worked for them

I have Tarrett front/rear sway bars and have them
* second to hardest in the front
* second to softest in the rear

But I am totally clueless on how hard I should make the PSS9

You should talk to SpecBox experts (BillP, and/or AndrewF). See what they do.
I don't have any clue neither.

but SpBox runs much stiffer springs...
so their chassis setup logs may not do you much good Chris.
I would set them at the mid setting (#4 or 5) to start and then go from there.
Probably will need to do a little test and tune for a few sessions.
Maybe Trigve will chime in, he has had PSS9s on his 2.5L for several years now and probably has some good data points for you.

Chris, you might get more feedback over on http://axpaddock.com
Lots of spec box racers and AX guys frequent the sight and are always talking setups for AX and track

my non-bsr thoughts

Like Dan said, the BSR runs much stiffer springs so our "stock PSS9" setups may not like BSR setups.

OK, since the PSS9's use higher numbers for softer, I'll number the sway bar holes that way: Hole 1 is towards the center of the bar (stiff), Hole N is at the end of the bar (soft).

PSS9's: I have been running at #2 on them for a long time (not quite stiffest setting).

Rear TRG bar: It has just 2 holes. Ran the first bar at 2 (full soft and safe). Eventually it broke, and I noticed how badly it understeered with no bar at all, hole infinity...figured since I can feel it, I should experiment. So on the replacement I tried 1 (full stiff and twitchy rear) and liked it. So I have gotten used to a little oversteer. Oh, that bar eventually broke, too.

(new) Rear Tarett bar: 4 holes. It's at 3 now which I probably chose because of wet weather last event, to err on the soft side on the rear of the car. I should maybe go to 2 now.

Front TRG bar: Holes 1-5. It's on 4 now, but has bolt marks showing I had it at 3 before. Not sure when I changed it, or if Tony C did it during recent suspension work. Car felt fine last event, so I'll leave it there for now.

I will definitely need to either soften the front or loosen rear more for the next trip to Buttonwillow, because understeer on the slow corners 2 thru 5 there is maddening!

Thanks Dan and TI for your tips

I was hoping I could try the settings tomorrow (4/20) at Laguna, but that didn't pan out (work got in the way).
So I guess I'll try them in Thunderhill on 4/30, maybe I have a chance then to pick Dan's and Bill's and Andrew's brain a little more ....
Let's hope that Paulette won't stick me into White (hint, hint) I don't want to get stuck behind one of them slow moving Turbos

Yeah, don't those slow moving Turbos just frost you......?
But they are running "flat out"
