How do subframe connectors help handling?

I'm looking for "exactly" how the benefit translates into "feeling" of the car. I know that they sure up the whole body of the car, but what does that equate to in handling.
Something like the explanation of bump steer, you can read about what bump steer is but it's entirely different to feel what it does (yikes) to a car.

For example: I have this kind of wave thing that happens if I hit a bump or manhole cover with one side of the car...it makes the whole car squirm or wave (best way I can describe it) on the road rather than just feel the bump.

Not sure I'm making sense but help me understand.
Thanks
Matt
