Bilstein PSS10 niggle - bits...
Nothing is as easy as it seems. :-(. Firstly after 500 miles of installation my fronts dropped 15mm? Is that much of a settling for the springs normal? I am to low now, I will lift back up and I guess I have to redo my alignment? Secondly, as the car is lowered does the steering get heavier? Also self-centring slower? As my car was settling (dropping) my steering was getting firmer. Increased load on springs? Thanks.

This is interesting to me as I just had the PSS10's installed on my 05 turbo. I have driven about 600 miles and have not sensed any additional drop at the front. Is this a common experience from others out there????

Depends on the spring rate, many will settle a bit. The steering feel is related to the steering angle sensor which needs to be reset each time the ride ht is changed. You need a PWIWS to reset the sensor, so might have to go to a dealer.

I would like to hear from the experts, but have read that any alignment or suspension change must be followed by resetting the steering sensor in the 996TT. Hopefully one of our resident tech gurus will chime in.

WARNING
Warning only applies to vehicles with PSM (only 911 Turbo)!
Danger of injury and damage to property due to malfunctions in the PSM control range if the steering angle sensor is not calibrated or is calibrated incorrectly!
Calibrate steering angle sensor with wheels in straight−ahead position with the Porsche System Tester 2!
The steering angle sensor actual value must be checked after a suspension alignment where no changes were made to the wheel alignment values!
I guess it needs to be done. I am off to dealership to get this reset in a few days when I am sure suspension is truly settled.

Today I was at Porsche dealer. Bearing in mind I've had PSS10's fitted, car lowered and have carried out an alignment, after they have checked my "steering angle sensor for calibration" guess what? No changes or recalibration of steering angle sensor or PSM were required. All perfect. So, this workshop procedure is probably BS and you needn’t bother.

I asked my tech about this today and he said that if the car has been in an accident and the front end is out of whack, then the steering sensor needs to be reset, otherwise probably not.

The SAS should be reset everytime you change the rd ht on a 996tt or c4s, when I didn't do it on my c4s with the x73, the steering was looser, once I reset it, tight again.
I think if the SAS is within spec it's bc you have a RoW car which already sits 10mm lower than a US spec car, so the difference is less.
