It seems that any of the Polyurathane kits are controversal. Opinions range from "your car will explode" to "it works great!" The rear trailing arm bushing is where you get the most difference of opinion. The Mugen one you have is popular. However you will also get people saying that the newer Honda OEM part is the same as the Mugen part (for less money). Apparently the newer Honda part looks identical, but the question is "is the Mugen stiffer or not". I have no idea what is true or not. Lots of opinions on H-T but who knows what is correct.
Yea, that's the big problem over there. On this particular issue, I've seen enough highly regarded people using the setup I'm going with to have confidence in it.
I have also seen the posts about the Mugen bushings supposedely being the same as the Honda but even the "credible" people aren't sure. Nobody has come up with any durometer readings I've seen and even then, that isn't a sure fire way to tell. My feeling is they are not the same but either one will work fine. I got a killer deal on mine from a friend in Charlotte otherwise I might have considered using the OEM part.
As usual with honda-tech, there seems to be some debate as to whether or not you can actually obtain the OEM rear trailing arm bushing. All of the parts diagrams I've seen don't list it as a separate part but I do remember someone posting a part number. I think the person might have had trouble actually getting the part but I'm not sure the issue was reported back as being resolved.

While researching this myself I found a few interesting URLs. This one mentions an interesting idea on how to "index" the rear trailing arm bushing. The idea is that if you lower the car and the bushing was installed with a factory ride height in mind that it would result in a twist or preload on the rubber bushing. I guess the implication is that the bushing will not last as long. Either way I can't see any harm in trying it.
I believe this to be the case with any ride height altered car. After doing any suspension work that involves removing a control arm or stressed component, I always let the car down with all the bolts loose. After rolling it back and forth to help it settle, I tighten the bolts down so when the suspension is at rest, there is no binding. It is a real pain with a lowered car but I think it definitely can take some suspension weirdness out of the picture.

I also have the ES master kit and I think that if you use their rear trailing arm bushings you have to reuse the sleeve. I most likely will go with the Mugen or newer OEM rear trailing arm bushing instead of the ES as well.
Hmmm That's the only one I haven't messed with yet but I'll take a look at it tomorrow. That's also the only one that has me a little worried about how to press it in-- I don't think my vise will open that wide. It also looks like it needs to be "clocked" properly which could present another potential issue. I may be calling Scott on that one depending on much trouble it is.
