I read after on this forum and as I see the car has nivomat shox.
These cost a fortune but some members changed the nivos to standard shox and heavy duty coils.
I was wondering which company makes standard shox and heavy duty springs to this car?
Thank you very much in advance!

Have a look on eabay, standard rear coil springs and shocks are available at pleasntly affordable prices for the 7/9xx series.
Nivos weren't fit for purpose even when new IMHO as they didn't actually level the car, only brought the rear to about 30mm below normal ride height when fully laden. As such, they don't level the car at all, just minimise sag when laden.
A decent set of normal springs and shocks does the same job without the need to carefully drive between 0.5-1.0 mile to enable the shocks to "charge" up from the bounce.
Meanwhile you run the risk of ripping the exhaust off or similar and feel seasick - not nice!

The rear coil springs for Nivos are deliberately wound longer and weaker than normal rear springs to give the extra movement the Nivos need to charge up from the bouncing motion of the car when laden. Using them with normal shocks will kill the normal shocks very quickly and give a saggy rear end to boot.
