Just received an email that my PSS10's have arrived , that's like only 12 weeks wait..... I almost gave up. Now to book in a fitting...yippee...

Just thought that I'd check in with an update on mine. I've maintained the same damper settings (which I am happy with) after the initial changes and found that on certain known bends I'm about 10kph faster, however, the car now has less traction. Before the upgrade my car would never spin up the rears, PSM on or off, it now does so on a regular basis. I guess that the stiffer springing is allowing less front to rear weight transfer.

Had the alignment reset today and we still cannot achieve stock settings with the coilovers at manufacturers recommended height.

Thanks for the update, 10kph faster through the bends is quite an achievement and a very positive outcome which is what really appeals to me.
Interesting regarding less traction, I would have thought the opposite.

Maybe the lower height settings is affecting not being able to achieve manufacturers alignment specs.

EDIT; Not sure how relevant this is but I came across this this morning, calibrate steering angle sensor.

Comment buy Jordanturbo on 997T section
"calibrate the steering angle sensor. Not recalibrating this will throw out your abs and traction control engagement points slightly. Most people would never notice but will make a difference if you really push your car hard or track it.I found this issue with my 996 C4S and the version of durametrics, my snap on scan tool, launch scan tool and every other one my shop had was unable to do it. I did my alignment and hit the specific numbers I was looking for then brought it to the dealership to have the steering angle sensor recalibrated"

Steering Sensor calibration finally working on durametric.

Keep us updated.

Also found this, to fix the issue. This is for a Cayman 2006 so not sure it works the same for our cars but its worth a shot.

Steering angle sensor (PSM)
The steering angle sensor must be re-initialised when the battery is disconnected and connected.
Turn wheels to straight-ahead position.
Switch ignition off and then on again twice.
Start engine.
From the straight-ahead position, turn steering wheel approx. 20° to the right, past the straight-ahead position.
Drive the vehicle straight ahead for at least one second at a speed above 4 km/h (2.5 mph).
The steering angle sensor segment is recognised again in this process.
Once the sensor has been successfully initialised, the fault code that is stored in the fault memory is documented using the fault deletion counter.
The fault memory erases itself automatically.
The PSM indicator light in the instrument cluster goes out.

For the 996T

I had them recalibrate the steering angle sensor after the first alignment when I set the shocks to their current setting. The 10 kph is on what were previously about 125 kph bends. I figure that the stiffer springs allow less weight transfer to the rear wheels which reduces the available traction. It certainly has less tendency to pull wheelies nowadays.

What damper settings do you have them on.

mcbit

Since mine are PSS9 on the front and PSS10, they reversed the setting between models. Front PSS9 1-9 with 9 being soft, I'm on 3. Rear PSS10 1-10 with 1 being soft, I'm on 8.

Thank you .
