Yellow speeds are a favorite amongst most 201 and 124 owners ranking next to the likes of Eibach, H&R and Bilstein. Its their pricing strategy that has given them the edge and yet, I've never seen anyone on the MB forums complain about these. A lot of the people who have these are running 3.2's-5.0's in those tiny merc's so it shows what these YS coilovers are capable of.
So an excellent purchase Farukh bro. Looking forward to these being installed.
