Why? It's hundreds cheaper to do the rear arm first and see if it solves the issue. If you do the subframe bushings you have to decide whether to do the m3 rear bar at the same time, and that's a big change to how the suspension works.

I would say to focus on specific problems you're having, and do the cheapest stuff first that addresses those problems. Tension struts (in front) and toe arms (in rear) are good candidates for directional stability and mechanical grip.

That said, it may well turn out that subframe bushings are necessary to get the result you want. It's not known, since no one's tried just installing the toe arm, without having done the subframe bushings beforehand.
