I put inserts in my rsx cause the front and rear mounts were torn and about half the rubber mount was gone in the front and it completely fixed the problem.
i have inserts in my DC2 and they were a pain in the A$% to put in but once i got a hold of a vice i was able to pop them in tight and bolt it right up.... dash shakes a little bit when i am at like 1500rpm but that is not big deal...
