It does.

You have to keep in mind that suspension is generally designed as a complete package for a specific car, ride height, handling characteristics, etc.

So you either use all the appropriate bits and set up pivot points around the original donor locations which may or may not work on the new car or, you start from a clean sheet of paper and design in the bits that you want to use ensuring the geometry functions correctly.

Loads of good books on how it should all work are out there

I have seen loads of good handling cars ruined by owners excessively lowering them and wondering why the thing doesn't handle well any longer. Reason is the geometry has moved outide the bounds of correct function and bump steer has been introduced.
