Chassis 156

Evening, I have to lower my Bella. Now I am thinking of how. The cheapest would be just springs, but my shock absorbers have already about 80tkm on it. Do you think it would make sense to buy only springs? At how much KM mileage, for example, do you usually replace the shock absorbers about? If they are too old then I grab to a chassis, but which? Please give me tips. Oh yes, by the way: Have asked my dealer the last time if he asked me the Novitec springs with 45mm Then he said FINGER WEG!! Not because the springs would be bad, but so from about 30mm deeper it can happen that the tires grind inside the shock absorber. So from 30mm a complete suspension in.
