This is how the height is adjusted as suggested by Porsche:



Taken from the tech spec booklet...link above...

Some people control the height by measuring from the fender to the center of the wheel hub. I don't have any numbers for that currently, but they're also available on the net.

There are no numbers iirc on how much height you gain per rotation of the screw. Its mostly individual to the car I guess, depending on the tires, pressure, weight of the car, gas tank level etc. All in all you have to raise it step by step. Or the other way - lift it on a post lift, turn the screws on max, so you can put car back on the ground and then you're able to lift it by a car jack, and then go down step by step... or when you can get on a workshop pit - or a 4 post workshop lift - is ideal for this job...
