As far as I am aware there was never an option for AMG suspension and brakes for the lesser models, bodykit, backbox, wheels yes.
Coil springs are specced by chassis, engine and the equipment level this generates a number which cross refs a pt. no. fundamentally there is no difference in the 202 AMG suspension and any model 202.
The springs are bought from MB not AMG, AMG is no longer a separate company and haven't been fully independent since the late eighties.
The problem I have found with MB dealers is that the parts people on the front counter are normally the less experienced employees I normally end up turning their PC round and navigate to the correct pages myself.
What did MB do confirm AMG?
