Do you advise getting new rear subframe bushings designed more for regular tires? Will just replacing the bushings be all that's needed?

Thanks!
There are several RSFB bushing options out there, ranging from inserts that fill the voids in the stock bushings, two piece units inserted from the top and bottom of the four corners of your subframe, and the ideal one piece units with various durometer or firmness.

The latter is labor intensive, and require a day of work, as the subframe has to come off ideally . The four bushings are reasonably priced. The popular choice is E92 M3 RFSB''s. I went with this option as a DIY, and it transformed the car. Bitch of a job though with improper tools...

Anyways, no need to go down this route, if you don't notice or can live with the washy and wiggling behavior of non runflats and stock RFSB 's...
