Springs and white markings

[mulrik]

I just installed new pads (upper and lower) on my rear suspension. I noticed the blue painting on the lower winding of my springs, and 4 yellow followed by 2 white strips (order bottom to top). Now, I know the white markings are there to help align the body height with the axle, but what should I align it with? Also, what are the yellow markers for?
Thanks!!

I have a 1970 280SL so I'm not sure the color chart applies to a 250SL.  Springs were color coded and matched in the factory. I replaced my springs with the progressive type.  My old spring were marked the same as yours.  One blue strip near the bottom followed by 4 yellow and 2 white strips near the mid section.  I don't know the meaning of the yellow and white markings.  The number of blue stripes indicates the notch position of the lower spring disc. 1 stripe indicates notch position 1.  2 stripes position 2 and so on for 3 stripes.  The notches are used for fine tuning the rear wheel camber.

THe yellow and white markings are probably refering to the spring rate ie Kg/mm or lb/in compression.
So if you have a 200lb/in spring it takes 200lb to squash it 1 inch, 400 to squash 2 inches etc etc
BMW use the same kind of thing, probably getting the springs from the same manufacturer.
what ever rate they are just make sure they all match.
