I need to change my rear springs... I called the dealer and I asked for a original spring but I asked him to raise my back by 4 mm which means an extra Burl in the shim.
My original spring was A2113240504 (1 x Yelllow/ 2 x Blue) and the top shim was A2113250484 (17MM). As you can see in the picture, my original shim had 3 discs and top hat which makes it for a total of 4 Burls.

The spring i got was A2113240604 with a 1 x Blue/ 1 x Green
The shim is A2113250384 with 2 discs and a top hat so total of 3 Burls (13MM)

Did I get the right parts?

I'm also attaching new setup.

Update : The springs dealer provided worked well. I also got the bottom shim which is aluminum that goes on the lower control arm.
I ended up exchanging top spring mount which has shims for the one that was the thickest available for w211 and it had i believe 5 (or even 6) discs. With rear hitch installed, wis called for extra disc so in the end I removed one disc and height was perfect in the back.
Very easy to lower the back of w211 if you choose to slam it...
