I have a 1995 C36 that came with a set of lowering springs in the trunk. They're purple, I was told they are Vogtland , but the important thing is they're about the same overall diameter with a smaller wire diameter with tangential ends like a 210. They are also nearly 2" shorter. My car has one tangential end with a flat end like a 124/201/129 etc and my collection of w124 spring shims work.

I've been told this is because I have an early 202 and these are for the v6/v8 cars. Can I retrofit these? It seems unlikely.
