So a customer of mine had some DA 1990 Integra rear trailing arms dropped off complete with brake cables, and after bolting them up it looks as though it will be impossible to properly align it because it looks like there will not be enough toe range to fix the crazy-*** toe in it has.

The camber also looks ridiculous as well, so my questions:

1. Do you need to keep any of the Civic pieces such as upper arm (the one people shim the bolts that connect it to the chassis) or toe link?

2. Are there any other modifications needed, such as a special SPC toe kit to get the proper toe adjustment?

I'll know for certain after we get thgis thing on the alignment rack, but I swear it appears this back end is all messed up and won't be able to be aligned.

I'm beginning to wonder if the parts were pulled from a flipped-over DA and possibly we've got some bent arms back here...

You just need to bolt the TA are up, the UCA and LCA and the adjuster from the Civic/CRX stay and bolt to the TA.

I have DA TA's on my CRX and everything is good. You don't need any special SPC crap.

The DA compensator arm is about 1" longer than the ed comp arm. It will bolt up but you'll never get 0 deg toe. reuse all civic control arms and you'll be set.

Thanks you thank you fellas.

I'm well-versed on my EG tech, and with my 1992 Cx I was able to swap all Integra parts on - all control arms and all, and the alignment was fine afterwards.

I'll swap the Civic stuff on and see if this one is still funky looking due to it possibly being bent.

Thanks again!

I'm also planning on doing the rear disc swap. I have everything except the ebrake cables and new trailing arm bushings, but these are the two things I'm concerned about.

I've read a post here where a guy was using the ES bushings on his CRX for auto x and said the free floating bushing did not stabilize the trailing arm as intended with a factory trailing arm bushing and it hurt handling. Is it that big of a deal that I should spend the extra cash on oem instead of ES or Prothane? And what about squeak? I know you're supposed to lube them liberally, but I'm talking a year or so after the fact.

Also, before I buy oem Si cables ($60 a side), do the DA cables (2 door) fit relatively ok? What did you guys use?

CRX Toad

You want the Si cables no questions about it.

I have heard every side of this story. If you search in the RR/AX we have covered the bushings thing many times. I just did the rear disc swap and I put OEM back in and I do track my car.

Here is a good thread https://honda-tech.com/zerothread?id=1508533 https://honda-tech.com/zerothread?id=1064620

Yes, the second thread is the one I read, was just searching in the wrong section to find it again. Thanks. OEM seems the indisputable best route to take every time.

So far the Da Integra e-brake cables were a perfect fit, and the e-brake functions perfectly.

I remembered that I did in fact leave the stock Civic upper control arms, but I do see the very clear difference between the Civic toe compensator arm and the Civic ones - I left the Integra ones on, so i'm swapping the Civic ones back in right now.

B18C5-EH2

Okay the car is going on the alignment rack right now, and I'll post back shortly if the alignment will be in perfect specs or not, but it looks like it should be no problem.

BRB.

so is it bad to have the rear lower control arm from the Da or it doesnt matter... cuz i had the same problem with my whole rear looking all crazy after the disc swap but i just keep the DA ones on

newaccordguy2003

its past 10 pm where you are, i sure hope you arent still working on this

I'm also interested to know the result.

I myself using DA trailing arms, but I wasn't sure whether my mechanic bolt it together with DA UCA/LCA or not. I did notice the toe was kinda off too. I'll ask my mech about this tomorrow.

Do you people get alignments? Cause after an alignment you know for sure?

Rukusmasta2

damn tryin to find a rear disc conversion thread i had saved cantfind it though sorry guyz,,,but ive done it on my EF and actually just did another one this week 5 bolts simple swap. on my boyz came out perfect no camber mine i had camber so a couple washers fixed it

HAHA didint notice he posted ...we just put his on this past week

Okay I just got done with the alignment.

Just kidding.

Seriously I went straight home after finishing the alignment last Friday, so here's what I've found to work:

DA complete trailing arms with e-brake cables
Civic rear lower control arm and upper control arm
Civic toe compensator arms

I've bolded the text above because that was the key to making it all work. Before I swapped on the Civic toe compensator arms the alignment was completely screwed and there is no way I could have gotten it within specs. After swapping the Civic toe compensator arms onto the Integra trailing arms I was able to perfectly align the car.

I believe the Integra rear lower control arm will work just fine, and as an added bonus it would allow you to run a rear swaybar too. The car I was working on was an Si with a rear sway already, so I didn't bother swapping them just for information purposes.

I also found out something VERY important in the process of swapping this stuff:

Have some new trailing arm bushings on hand, because you'll rarely see any worth a crap these days.

Also noteworthy is that the DA trailing arm bushings are NOT the same as EF Civic ones, so you must buy some for a DA only.

I had already purchased some new trailing arm bushings, OE Honda ones, for the EF thinking they are the same as DA Integra ones, but they are not at all. The DA Integra bushings are NOT available from Acura or Honda, so I had no choice but to use poly bushing kits from Prothane. Normally I would not do this, but theis car is never going to see any serious handling so I doubt bump steer will ever rear it's ugly head for this car's owner.

Overall the swap isn't terribly difficult, but for me it was kind of time consuming mainly due to the routing of the damn e-brake cables. Also the proportioning valve is a motherfuucker because this car has A/C and the lines are right up against the damn prop valve.

One last thing I've noticed, and it may just be this guy's retarded offset wheels playing tricks on my eyes, but it LOOKS like the rear track may have been widened with the Integra rear set-up.

Has anyone else noticed a slightly wider stance out back after doing the Integra rear disc conversion?

i have heard that from a few people how it gets a wider looking stance and it seems as if mine and my boyz did slightly. Yea the hardest part of the whole swap is hte damn cables, pretty self explanitory 5 bolts ya know brake cables can be a bitch but a for you bro

This is incorrect I just purchase the bushings from the local Acura dealer here when I did the swap 3 weeks ago on my car. They are still out there and available.

DA TRAILING ARM BUSHINGS ARE AVAILABLE @ ACURA

I will get the part numbers off the bag they came in for everyone.

Please post that info, because I called THREE local GA Acura dealerships, Baranco, Ed Voyles, and Nalley Acura - none of them were able to pull up the separate bushing itself. They only offer the complete trailing arm.

They all checked the bulletins too, but none were avaiable to pull the trailing arm bushing part number alone.

...now Honda on the other hand was able to get me the EF number instantly.

Thanks for the info - I'll be sure to call all three guys I spoke with about this just to prove to them I was right.

I had been telling them I knew they were out there, but they kept telling me I needed to supply them with the part number!

WTF?

Installation trick: do not remove the compensator arm (the farthest forward arm) from the body of the car (do not even touch that bolt) and you wont have to get an alignment.

If you do not loosen the bolt for the alignment adjustment, then how do you get the clearance needed to remove the bolt that holds the toe comp arm to the front of the trailing arm? Is there enough give in the rubber bushing to pull the arm that far down w/o having to loosen the alignment adjustment bolt?

Anyways I guess I'm spoiled because I have a rack here, so I do alignments on my own cars far more than most people have them done.

Plus on this car particularly the alignment was already screwed.

Leave that as the last bolt and you can swing the whole thing down enough to get that bolt out. It is easy to do but I still got an alignment just in case.

And yes you are spoiled that you have rack and can do the alignments.

the DA e-brake cables can be used, I found that when I did mines I criss-crossed the lines into the inlet holes of the cab. By doing that it will atleast account for some of the extra inches in length that the DA has.
