How to Calculate Spring Constant for a Vehicle Suspension?

[QUOTE="Mechaman, post: 5921447, member: 533291"] [h2]Homework Statement [/h2] A mass of 115kg is to be suspended from a spring. When the mass increases to 575kg, the spring will move. Find the spring constant k. (This is not from a textbook, it is a project problem for a vehicle unloaded and then loaded on the same spring). y1 is the maximum height I have but y2 can be changed if needed. [ATTACH=full]218411[/ATTACH] [h2]Homework Equations[/h2] (y1-y2)k = mg [h2]The Attempt at a Solution[/h2] (0.2)k = (575)(9.81) k = 5,640/0.2 k = 28,200N/m This looks very wrong, comparing to a website that sells a spring holding 1300lb (590kg) gives a rate of 300(136kg/m) or around 1,300N/m How is my answer so wrong?
