They might require a total dissembly and re-greasing in the near future, and they do transfer a lot more tyre and differential noise into the cabin.
Unless you can live with the noise and you've got a 10.000 kg press, car lift and alignment rack I wouldn't recommend it.
I do recommend switching the rear subframe bushings for the stiffest you can find, preferably aluminum ones. - getting rid of the rear bounce makes the rear shock absorbers actually able to do their job!
