I have been running cut stock springs for over a year. The ride was fine on the smoother roads but I wasn't happy when hitting bumps. The KYB shocks helped a lot but I have now decided to see if any more improvement is possible and try some new springs. After reading as much as I could on here and on the Benz sites, I have decided to give Vogtland springs a try. The have been shipped and I should get them any day now. I will let you all know what I think of them.
