Junk.

Stick with OEM or HardRace rubber bushings.

Unfortunately I don't see any HardRace kits for EG Civics on eBay at the moment.

I recently saw a DC Integra kit for about $180-$190 so EG should be the same.

i have urethane bushings in my car, but only in certain places. the car feels very nice on the track. i have hard rubber bushings in the LCA's and urethane in the FLCA, rear caster bushings, swaybar mount bushings front and rear . the rest are oem rubber. its been through numerous track days and daily driving for about 5k and no problems yet

This looks promising. Not sure how I feel about the TA bushings, but if the rest can hold together as well as OE, count me in.

Interesting, did they just release those recently? What's wrong with those TA bushings?

rear caster bushings? There's no such thing as caster on wheels that don't steer

same here, mine are great. i still find it odd that honda-land is the only place ES seems to be disliked that i have ever came across. the miata, corvette, mustang, volkswagen and countless others use them at my local track. i think some of you guys are trend followers who hate them. if enough people say they are junk, you don't like them anymore.

the good side is that they flex less and allow you to keep tire wear a little better when you are autocrossing. the bad is that they can squeak if they aren't greased right. some find them too firm...or so they say, i often wonder what spring rates these guys use.

Trendy? Um, no.

You weren't even registered here when the subject was being discussed and researched on this forum. It's well before your time.

Years ago, club racers who frequented the H-T Road Racing & Autocross forums (members who are no longer with us because they moved on to another forum) discovered the binding issues with the solid polyurethane trailing arm bushings sold by Energy Suspension and Prothane. After replacing these with OE Honda or Mugen rubber TA bushings, some odd handling issues were solved on a number of Improved Touring and Honda Challenge-prepped cars.

Upon further inspection, multi-axis binding and longevity issues were discovered with several other bushings in the wonderfully complicated mechanism we know as Honda's suspension. That's not to say that polyurethane bushings are bad for every application; there are indeed several points on these cars where polyurethane can work properly and is beneficial to use. However, you have to know where to use it and where not to use it. Most current IT cars are using a mix of rubber, polyurethane, and spherical bearings. There were several threads on this topic and quite a bit of information was shared. Search the forums, it's there.

Apparently you haven't bothered to do the research yourself. I guess since everyone else you know (blindly) uses them, they must be good. Talk about trend following?

Wrong, one individual named Scott suggested ES TA bushings bind and all the followers perpetuated the sentiment.

Show me some conclusive substantiated data, lemming?

There is nothing fundamentally wrong with ES trailing arm bushings on a Honda for a general consumer.

yeah whatever. I'm sure this is the guy you were referring to. He mentioned RealTime Racing using rubber RTA bushings on their DC Integra race cars. That's gotta say something when a successful racing league is NOT using polyurethane in that location. https://honda-tech.com/zerothread?id=493789

This guy actually swapped out poly bushings in favor of Mugen rubber bushings and reported much better handling at the track. Track or not, I refuse to install something on my car's suspension that does not allow the suspension to move properly.

https://honda-tech.com/zerothread?id=1589298

There is another thread that I can't locate at the moment showing the ES LCA bushings on an ITR after only 2 years of use (periodically lubricated), and they were completely trashed.

More bunk, all your references point to the same source, the one individual I already mentioned.

Show me some empirical numbers?

Were the ITR RTR cars sponsored by Honda or ES? All competition cars use the best parts available regardless of sponsorship, right?

Sure sphericals are a more precise part for a RTR race car, however for a street driven auto, poly is the longest lasting most economical, performance choice.

I will agree there may be an increased amount of friction or resistance in the direction of certain suspension movements with poly TA bushings however on a street car, driven under normal operational conditions, their are no significant binding issues with poly TA bushings.

im not huge fan of es BUT purely personal preference due to dam squeeking you get in daily use (yes, plenty of supplied grease was used but dissapears after couple months), i use mix of oem, hard rubber and es on my car

they are good value though and i guess no 1 reason they sell so well and easily available which is great for the customer

regards longevity i cant personally comment, can only go off stuff you read on forums which "suggests" es wears much quicker than oem/hard rubber BUT again on forums as well as great info so there is lot of misinformation so this point can only be taken with pinch of salt unless you have personal experience

I've been running es rta bushes for about 2 maybe 3 years and look like new still but i don't think that length of time constitutes enough time to review longevity in comparison to oem

as for this binding comment, seems this stems from comment on net and stuck in peoples heads, ill be honest. i fitted es rta bushes and knew nothing of comment and had no issues, i then came across comment more and more on here and it stuck i my mind and purely due to it playing on my mind (no real world issue) i wanted to switch to oem

BUT

after 2-3 years of road use everyday , a few trackdays and trip to ring I've had absolute no issues so decided to keep them

everyone has their personal experience and this is mine, some like em some don't

ah TunerN00b found the post I was trying to find earlier regarding polyurethane bushing wear.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by DB2-R81 &raquo;</TD></TR><TR><TD CLASS="quote">More bunk, all your references point to the same source, the one individual I already mentioned.

What do you want to see? The 2nd link I posted above is shows real experiences by a real person who swapped from poly to Mugen/OEM rubber RTA bushings and reported BETTER track handling. If that's not proof enough, then I don't know what is. Yes there are differences between track use and street use. But if the OEM RTA bushings perform better on a track, why in the HELL would you want to use poly on the street? Also I did not see any references to Scott in rmcdaniel's post.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by DB2-R81 &raquo;</TD></TR><TR><TD CLASS="quote">Sure sphericals are a more precise part for a RTR race car, however for a street driven auto, poly is the longest lasting most economical, performance choice.</TD></TR></TABLE>

Absolutely not. Polyurethane does not last nearly as long as rubber bushings when exposed to normal street use and all weather conditions. Take my polyurethane shifter bushings as an example. I replaced the old original rubber bushings in 2001. After 7+ years of use, they were a little dry but really not that bad. Just 5 years later, I found my shifter bushings completely dry rotted, crumbling, with MUCH more freeplay than the rubber bushings ever had. I have since switched back to new OEM rubber bushings and it feels 100x better.

The rest of my suspension is still running on original rubber bushings. Yes they are 14 years old and have some dry rot and need to be replaced, but they're nowhere NEARLY as bad as the 2-year old poly bushings shown in the post above that TunerN00b linked, which is the one I was looking for earlier in my previous post.

Replacing poly bushings every year or two, or using rubber bushings that last many times longer. Which one sounds more economical?

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by DB2-R81 &raquo;</TD></TR><TR><TD CLASS="quote">I will agree there may be an increased amount of friction or resistance in the direction of certain suspension movements with poly TA bushings however on a street car, driven under normal operational conditions, their are no significant binding issues with poly TA bushings.

</TD></TR></TABLE>

If it binds on the track, it's going to bind on the street. No way will I ever use those on my car, nor will I ever recommend them to anyone else. I'm still going to recommend stock rubber as superior to polyurethane for many reasons.
