A critically damped suspension will be back breaking and the vertical accelerations happen too quickly for a driver to really respond to them.

Yeah, the impulse looks good, but the step reponse should have a final value of 1, not zero. I'm not sure where the error is coming from though.
Edit - just found the error. I made a mistake entering your transfer function. I'll upload new plots in a second.
