I have a question... front lowering is ~610mm.
Rear by software I do not get my desired lowering.

The vehicle is currently too low in the rear, I tried 590, an error message appears that it is too low a number, I did 610 as in the front and the suspension went up, I did another 610, the suspension went up again about 1.5cm, I did another 610mm and the suspension went up again, that was high as a bus.

How can this be?
Then I wanted to make something down and have made to test 630 to drive down piece by piece, nothing has done, also again 630mm made, nothing has done, have then 670mm made, he has moved only ~2cm, wanted to make 690 to drive down again 2cm, he has made again nothing, wanted to make 710, there came the error message that 710 is too high a number.

So no matter what value I enter between 600 and 700, the never makes the desired height... alone that I have made 3x 610 and the each time became higher and higher... what am I doing wrong?
