Only if the Focus had rear struts. It has shocks...so to be honest it would take something triangulated to add any real stiffness to the structure.
Tires/wheels, alignment, Good dampers and a RSB are the things to get first...in that order if not all at once. Then front camber plates would be next for handling...
