The hot-rodder term 'instant center' is a contraction of the much more general term 'instantaneous center of rotation' which is used when describing 4-bar linkages (a 4-link rear suspension is a pair of 4-bar mechanisms in parallel). The reason for the word 'instantaneous' is that with a 4-bar the center of rotation constantly changes with the motion of the links. This is really the purpose of the 4-bar mechanism, you can get them to trace out all kind of motions by changing the lengths, angles and positions of the links. For a leaf spring or ladder bar all you have is a Center of Rotation.
