You can use the Powerflex differential bushings with the MRF Engineering solid sub-frame bushings. We have done this on a few cars now and the owners love it as well. Most of the benefit comes from the sub-frame mounts anyway, the differential bushings are the icing on the cake. Most prefer the feel of the Delrin differential bushings and are willing to deal with the slight increase in differential gear whine.
It's really a subjective matter though. If one is willing to deal with a louder exhaust, then dealing with some more diff whine shouldn't be a concern.
