I know the older (not sure what years) civic/integra trailing arm bushings were somewhat defective and the would start to come apart prematuely. that bushing was redesigned at somepoint and if you by the honda bushing it should be more robust than the orginal.

There is a debate about whether or not using a poly bushing for the RTA is a good idea. I personally think it is fine, but you certainly can't go wrong with OEM.
