I fitted some spring assistors to my 190E last night in anticipation of a overladen drive to Croatia later today.
They were a bit of a bugger to fit, lots of cursing and skinned knockles but got them done in the end. Took ten minutes on one side and an hour and a half on the other - go figure?
The car does sit an inch or so higher at the back now unladen. The ride doesnt feel anyway compromised. The big test is what its like overloaded with stuff on the long journey south.
