560 rear end height adj?

[RSA560]

Hi Guys,

...new to yr forum - it is superfontastic!

I've done extensive searches on the SLS system of the 560's - to no avail. I would like to learn how to adjust the rear-end for increased height to combat the annoying sagging - there are no leaks in the system - although the left rear is sagging more @ 1 cm than the right.
In any event I would like to see if I can raise the rear to at least bring the car up to level again. Id say the rear-end is currently 1 cm lower than the front.

The 500 SE had new air-cells put in last week - it is back to magic-carpet ride status again. Also, its rear-end seems to sit about 1 cm higher than the front which is great. It really makes it drive better with a slightly raked forward stance.

FWIW, the 500 sits about 3cm higher at the rear than the 560.

Any advice greatly appreciated!
