Our CRX has the bushings in back along with a few other places. It is a race car and the stiffness driving it home from the fabricator when it was done was more than anyone would welcome on the street. Why was it driven home-because the trailer had not been delivered at that point. I agree that sway bar and end link bushings should be upgraded even on a street car that sees little track time. Otherwise the stock bushings or slightly stiffer Mugen type are fine even for track use. Our Prelude is multi-link so I really do not plan to upgrade them.
