https://en.wikipedia.org/wiki/Mass-spring-damper_model

The forces of that ^ in English.

kx is the spring rate - note it's a function of displacement (x) with a spring rate k - the force changes with deflection. --the further it's pushed, the higher the force.

cx(dot) is the damping force. The force there is a function of damper restriction (c) and changes with velocity (x-dot) --the faster it's pushed, the higher the force.

mx(double dot) if F=ma (sound familiar?) it's the inertial force. --the faster it's accelerated, the higher the force.

So what that all says is; you change one part of that equation (a spring, shock or the unsprung weight) everything changes. - the freq. response changes (over damped, under damped...)

And there is also that the simple spring damper mass system is attached to a big flexy mass (the car), and add the complexity of the tire being its own mass/spring/damper system that changes with tire temperature and wear.

Corner balancing is but a crude measurement.
