WOW!!!
I have been tracking for a while with the US M030. Last Friday I had the Pss9 (Gert) installed and the car cornered balanced.

Today I took it to the track. It is as if I bought a new car. Started with the rears set at 4 than moved to 2. 2 is where it will stay.

Is US M030 ROW? how much better is the pss9 than US MO30? it must certainly "feel" different but how is turn in, under/oversteer?

I just got my PSS9 installed also, looking forward to this coming weekend where I can test it out at the track (Summit Point). I totally agree that its like a different car. Most of this, I think, is because you can actually get some negative camber. My car now has -1.4 front and -2.5 rear. Its like it has found magic grip. Makes no sense to me why my car from the factory had 0 degrees camber!

I was running 3/4 settings on the street, but changed that to 2/2 and though its stiffer, I really like how it handles and rides.

What are your alignment settings?

US 030 is NOT ROW...ROW stands for Rest Of World, so the ROW 030 is lower than the US version due to US traffic/vehicle laws about bumper height. Opinions vary on which setup is the best, but since PSS9 is adjustable it has an advantage over ROW 030

roberga,

Yep, you said it. I'm running ROW height and 4/4 for the street. It's a whole new car. Is this the best bang for the dollar, or what? Enjoy!

c70Pete: US is taller then the ROW. There is no way to compare the PSS9 to the 30. The ride ids fine for me. If I wanted a soft ride I would drive my wife's MB.
It feels very different much more responsive to minor inputs. The body has zero roll. By adjusting the stiffness you have controll over uunder and oversteer.
Darren: 25 inches center of front wheel well to ground 25 1/2 rear Yes I now must be more carefull with the GT3 aero.
Front camber -1.3(L) -1.2(R) rear: -1.8(L) -1.9(R) chassis cross 50%@ 1563

Interesting....So I'm running about .7 degree more negative camber, I guess I'll have to try it at the track to see how it works out.

I got my ride height to 25.25 front and 25.75 rear. That is as low as I think I can go -- I scraped the front spoiler making a turn off of my street...have to be very careful.

One thing to watch out for: I checked the ride height from the fenders and also from the jacking points underneath. The body work can often be a little differently aligned. On my car, the rear fenders and the jacking points seem to be even on both sides. On the front, however, the right front wheel well is 1/4 " higher. In other words, I set the front ride height at the fender to 25.25, then checked the jacking points and the right side was up 1/4" higher. From what I understand (from a friend who works at a Porsche shop) this is even more of a problem on older cars.

Q: What is the word on the GT3 sway bars? The car with the PSS9 (as was mentioned) seems to have very little roll. Do these make any difference?

Probably to keep tire wear more uniform across the tread face........

Our cars came w/ 0 camber up front with -1.5 in the rear to induce understeer. This is due to the numerous lawsuits Porsche received w/ the earlier 911's.

My PSS9 settings are:
ride height: 25.25 front / 25.5 rear
front camber: -1.4 (max possible)
rear camber: -1.1
front toe: 0
rear toe: slightly in - I cannot remember the exact setting.
dampening: 2 front / 3 rear

These were the settings recommended by a shop that races a 996 Cup Car. I inquired about less negative camber in the rear and they said that the car will perform better with less in the rear.

I've been to 2 events since the install and am very happy. I am thinking about the adjustable GT3 sways but will wait until after I do more events to decide.

so I take it from all the positive feedback that PSS9 is superior to ROW 030!
