Uneven Height

[kingjooz]

I've got an NA6 with Koni Yellows with lowered king springs. However the driver side sits about 10-15mm lower than the passenger side.
I did a physical check on the shocks, no leaks visible around the shocks itself, however ive noticed that the springs on the driver side (front & rear) are more compressed than the passenger side (front and rear), hence the uneven height.
Not sure why this is happening. Any help or advice would be much appreciated.
Thanks!!

Do the springs have any numbers on them?

Does the drivers side sit lower with or without the driver in the car?

This is very common on the NA6 & NA8 - some discussion here:
