Ah! That explains a lot. In the USA,
front V36-0361 rear B36-1385 - these are HD's (black)
front V36-0365 rear B36-1470 - these are Sport (yellow)
The shocks need to be measured out of the car, btw, for comparison purposes. If your Mercedes shocks (out of the car) are the same as "Sport" Bilstiens, they are not Mercedes "Sportline". Can you find a Mercedes part number anywere, stamped on the shocks? It will be in the format 124-xxx-xx-xx. If you have standard MB shocks, the Bilstein Sprints or MB Sportlines will be much better with a lowered car!
