Does anybody have information on the appropriate front ride height for the S212/W212 AMG Sport model?
Nearly two years ago, my S212 failed its MOT due to a fractured front spring. Upon attempting to acquire replacements, I consulted many suppliers and became convinced that it was imperative to emphasize the need for them to conform to AMG Sport specifications. Two vendors did not respond, while the third, Evelex Ltd, said they could get a pair, but at a higher price and with a delay of several days. I requested a verification, and they confirmed that they were indeed the correct springs.
Following the usual wrestling with dual sets of DIY spring compressors, the new springs were successfully installed on both struts, and I was rather glad to reattach them to the vehicle. I saw that the front was lower than I recalled, and the front suspension seemed to produce a tiny knocking sound on uneven road surfaces compared to previously; nevertheless, I dismissed it thereafter. The arches are almost aligned with the top of the front tires, with just little variation at the rear.
This year at the MOT, I received an advice on both front springs; the tester saw that the front was much lower than previous S212s he had seen and inferred that both front springs may have lost one or two coils.
Significant time has elapsed to approach the seller again; nonetheless, I am more persuaded that they may have overlooked the VIN number and just focused on the AMG designation, thereby providing me an E63 AMG springs.
Verifying the VIN independently indicates the suspension as 677 AVANTGARDE/STANDARD SUSPENSION. Research indicates that the component number A2123211404 pertains to the springs, which are abundantly available and far less expensive than my last purchase made a couple of years ago.
What is your opinion? Should I conclude that the vendor provided me with incorrect springs, and if I replace them with a regular specification pair, would it enhance ride quality and restore the appropriate ride height?
