This was certainly my expectation. Intuitively how could they not given how much stiffer they are than the originals? In fact though, I can't tell the difference in terms of NVH with the M3 bushings. When I made the change it was the only change I made at the time. Others who may have made changes to the rear bar, shocks or springs at the same time may have a different experience, but it may be from those other changes. A far bigger contributor to the NVH quality of your ride is your tires. NVH should not be a reason not to change your rear subframe bushings to the M3 bushings. I have no idea if this is true of plain urethane bushings though.
