The invention relates to a method for optimizing the residual stress distribution in spring elements used as vehicle suspension springs, especially in the bar cross-section of helical compression springs of relatively high strength, the helical compression springs being set and shot-peened. To provide such a method which allows a further improvement in the life, in particular, of helical compression springs with strengths of Rm /= 1800 N/mm2, the helical compression springs are fed to the production steps of setting and shot-peening with a predetermined strength profile related to the bar cross-section.
