Typically if someone replaces the stock springs with lowering springs they also install shocks designed to work at the lowered ride height. Bilstein makes a set of shocks/struts designed for lowered W124's. If the installation was done properly the person should have tightened the suspension with the car sitting at the new lowered ride height to insure the bushings are not preloaded. The only other requirement when lowering the car significantly is an alignment.
