I just did this last week on my e46 M3. Replaced all rear bushings. Everything, then did the pre loading and tightened. Peter (A1exander) taught me how.
Once the car is lifted in the air, loosen up the suspension etc. When you are done and want to re tighten everything, make sure you use a jack or something to lift the wheels up, so they are in their natural position as if the car was on the ground. Then tighten everything up. Do not tighten with the wheels and suspension hanging down. This will not tighten them correctly.
When installing new springs it is also important to preload the suspension before tightening all suspension pivot point bolts. This can be easily done with the full weight of the vehicle on its tires on an alignment rack, or if the car is on a lift or jack stands by using a jack to lift each suspension corner to then tighten all the pivot bolts at each corner. Proper suspension preload will ensure a more consistent lowering and also help the pivot suspension bushings last longer.
Hope this helps.

WHERE is this vibration. Down the center of the car?
Might be Center bearing on the prop. Or Guibo (flex disc) that sits between propshaft and gearbox.
