has anybody used these?

i'm considering doing a rear disc conversion on my wagon, and if i do i'll build a set of trailing arms and then swap them (so the car won't be off the road).

so, since my current bushings are shot, and any on junkyard arms would be shot, i'm trying to decide what to put in, and these look rather sweet.

i'm assuming the "recommended for track use only" text is to release them from liability: but any reasons you wouldn't use these on the street?

 

just get the mugen ones everyone I have talked to loves tehm. 250 bucks.....damn

they have no flexability, so your ride will definatly became pretty harsh.

 

I will trade you my mugen ones if you buy me those

Honestly the ride is going to suck unless you are running a strictly track car get the mugen ones http://www.kingmotorsports.com

 

i got the energy suspension bushings. they look nice but i haven't installed the arms yet so i dunno how they perform just yet. the real racing guys love the spherical bushings (from what i've read in forums) but i imagine for a street car they are pretty harsh. and the mugen ones prolly kick *** but cost a pretty penny like everything else mugen.

 

I got prothanes on a street car. The harsh ride doesn't really bother me because I avoid the shitty roads

I wouldn't make the assumption that "recommended for track use only" is a liability issue. Frequently, the shop might actually know what they are talking about (I don't know if that's the case for the above shop, but I agree with their recommendation). Those RTA bearings function very differenty from the OEM application and will not perform as intended on a car that is setup for the street. They are also not maintenance free. These types of bearings will require regular lubrication and cleaning or they will wear quickly. Finally, you had better have a really good reason to spend $250 on your RTAs and I can't imagine what reason that might be for a street car other than bragging rights (not an accusation, I just can't think of any other reason).

Also, I suspect the ride quality is bogus. Frequently the assumption is made that "racing" parts always make any car handle better at the expense of ride comfort. That statement couldn't be more flawed. "Racing" parts are designed to work together, not one at a time, like "safety" parts. Not all safety parts will make you safe, and not all racing parts will improve performance and hurt comfort. I assume that concept came from the loss in comfort when using high spring rates, but I bet you could install these RTA bearings on a completely stock Civic and you would never feel the difference in comfort.

Here's a lot of very good information on RTA bushings that I won't take the time to retype: https://honda-tech.com/zerothread?id=493789

And some additional information on rear suspension dynamics: https://honda-tech.com/zerothread?id=606414

If you're going to spend $250 for some bushings/bearings, at least take the time to read what they're for.

 

are the ES ones any good???

 

Good threads Travis thanks

OEM Honda...

 

any other thoughts on ES TA bushings? i have the master kit and love it, but seems these are too hard and make the car unstable at higher speeds? im confused
