Replacing rubber support for the springs

[lagolag]

I have started replacing warn chassis rubber parts on my my 56 year old 230SL and when I found out that there is 6 different heights (20 - 32,5mm) on the front upper coil spring support and  three different heights ( 18 - 32mm) in the rear I need help to choose the correct heights for the front and the rear. Some of you out there most likely has run in to this  before me, please chair your knowledge

Attached is a Picture from Niemöller in Germany showing the 6 different for the front

The different thicknesses are for fine-tuning the ride height. Start with the middle size.

Also the rear retaining cup that the rear springs sit in have 3 adjustable positions. I think by factory default they are in highest position

Isn't the thickness of rubber base and the trailing arm setting based on the color code painted on the spring? My understanding is that the color code on the spring represents the spring force of each individual spring and then you use the chart in the BBB to match the proper thickness of rubber and also the trailing arm position. Please correct me if I am wrong.
