V 60 restless steering

Dear reader, I have the feeling that the steering wheel reacts very restless and sensitively, especially at higher speeds and in bends, which leads to a subjectively uncertain driving feeling. Since my V60 D5 AWD is unfortunately not equipped with the driving dynanic package, I lack in the setup the adjustment of the speed-dependent steering. Now good advice becomes expensive. – Do you think that the “driving feeling” changes by the installation of a dome strut (I am with the R in the package).
