For the rear subframe, there is about an inch or a little more of travel before the bushings contact the body. The subframe spacers eliminate the majority of that play and thus firm up the rear end. If you have wheel hop around corners, adding sub frame spacers will definately eliminate it.
As far as getting rid of all your busings, it's a long and painful process but cheap if you do all of the pressing yourself.
