the shimmy can have many sources and any slack in the front suspension/steering can allow it to start, m5 upper control arm bushings proved themselves longer lived then the green 740 bushings back when i worked on bmws for a living, weak upper bushings can cause or be damaged by the shimmy, larger and heavier wheels magnify the issue (higher road force, more then balance being the concern, a wheel assy can balance at 0 but be out of round and cause a shimmy) swaybar links won't cause a shimmy for the record
