Hello, someone from you already has experience with the AMG Performance Package? I’m now 3 J and 120,000 km with the SLK 350 and now would like to switch to the SLK 55. I have the standard sports suspension of DC. I can only advise anyone from it. Just hard and poorly tuned. Long motorway curves with bad underground drive the sweat on the forehead. He then simply loses the ground grip too quickly and is transferred. I am now a WE a SLK 55 The chassis was much better already. Think now, the AMG Performance Package with me. Is there another chassis installed there. Who has driven it before and how is the road position especially on motorways at speeds greater than 200Km/h? Thanks for reply LG Bernd
