Why do I feel softer and more roll on Swift springs compare to same spring rate of other brands?
Swift engineers design all of our coilover springs to be a true linear spring. Unlike most other brands, Swift springs rates are tested to stay linear from 20% 80% of the available stroke. While most other brands claim they have linear ratings (after testing) turn out to have a progressive rate change the further you compress down on the spring. A constant (linear) rate change will always feel softer then a progressive rate change. .
