Replacing shock absorber with spring and damper

Hello Solidworks Community,

I want to do a motion study, with a car that has to drive over a roadbumper. But to do the study, i would like to replace the 4 encircled shock aborbers with springs and dampers, as the car just collapses with the dampers only.

Any suggestions, as how to do this in a motion study? Would you guys completely delete the shock absorbers, and replace them with springs as seperate parts? Are there a smarter way to do this?
