is it the da setup that will only fit?

 

Usually people go with the DA rear disc, or CRX Si rear disc. The whole setup from a DA will bolt right up tho, but with a CRX you will need e brake cables from the DA. I just did this conversion from a 1990 DA and used everything, trailing arms, brake lines, e-brake cable, ect. The e-brake cables bolt right up too so theres no issues there.

 

On a crx, you need to use the toe arm from a crx, not DA.
Also, the DA ebrake cables are like 8-10" longer, kind of a pain to deal with, but usable.

 

i have a ef sedan so lets get the clear

i found this. can i do this to my ef sedan?

DA E-brake cables are only too long for the crx, and since he has a sedan he should be fine with DA e-brake cables. IMO to the OP, go to a junk yard, find a DA, and take everything on the trailing arm except the arms. This is all you will need from a DA

E-Brake Cables
Trailing Arms with everything on them, rotor, hub ect.
Brake Lines
***DO NOT USE DA ARMS*** the camber and toe arms are not the same for EF.

Also since your an 89 I think they still used different LCAs than 90 and 91 civic so you will need the LCAS from 90-91 civic as well.

For conversion from a CRX you want

DA E-Brake Cables
Brake lines from a DA
Trailing Arms from CRX and hubs rotors ect.

Essentially either way you need the DA brake lines and cables since they will bolt right up, crx lines and cables are too short.

I just did this conversion and all I changed was the pads on them. I didn't up the master or the prop valve, its highly recommended but not 100% required for daily driving.

 

Do your research before doing this swap. I was all excited about it myself and had it done a decade ago....but, looking back, i regret it.

Doing this conversion will give you zero added performance, it is simply for looks. On a typical Honda, 75% of the braking is done in the front anyway, the rear play a small role in helping keeping the car balanced, and because these cars are so light, the drum setup do the job just as well. In fact, back in 1990, when the new refresh of the crx si came out with the rear disk setup, it stopped 3 feet longer than the previous 88 and 89 model with the drum setup, LOL

So again, i think......i spent money, i used my time, i added weight to my car, and gain no performance...but it looks good

 

omg... THANK YOU! I got a little razzing on my build when I kept the stock drums, they didn't believe me when I said it really wasn't worth the extra work/money.

 

Well said !

 

yes i feel the same way i spent a couple of hundred dollars doing this swap and i dint see
any improvement

 

Drum brakes are also a pain in the *** to change in comparison to disc.

 

i have a 90 sedan but i created this account when i had a 89. so no added performance just looks. im ok with that. half off sale is coming up at my nearby junkyard anyway. but ive read that civic disk brake trailing arms are 7lbs lighter each. so would like to find those if they will fit.

could i use the da lca's with adjustable uca's and camber bolts and have nice stance?

 

lol, one is not much hard than the other to change than the other. Also, this is something that gets done, what? ....every ten years ;P It's really not much of an inconvenience

 

actually its the other way around, disk brake set ups are 7lbs heavier each side. there might not be much to no performance gain but in heavy braking it does reduce the nose dive a car does. annnnnd it also looks good lol

 

i thought i read that the trailing arms from a civic with stock rear disk are 7lbs lighter than trailing arm from a da with rear disk

 

Id by UCA you mean the camber arms then sure, theres no camber bolt like in the front, usually the rear is an arm that can either extend or compress more to add or reduce camber.

I also wouldn't use the teggy LCAS. If you have a 90 sedan you don't need to you can just use the ones you have. The only reason I said get new ones is because 88-89 use LCAs that are different and kind of "bock" style

 

 

Did you read through that whole thread though? You don't need to have 15" brakes. Also this topic has been covered to death, you could search and find threads on this already

Read through these threads and you should find most answers to your questions...
Also what are you wanting to do? From the looks all you wanted to do was swap to disc brakes, but you qouted that thread with the 15" brakes so did you want bigger brakes after you swap to rear disc?

 

trailing arms dont change, theyre all the same. what chages are the hubs. the drum hub setup is lighter than the disk hub setup. so both cars have ideally the same weight with the same setup.

when i did my swap in the back all i did was switch the hubs, didnt even mess with the trailing arm. most people dont do it this way because they dont know that all trailing arms are the same

 

siiik is it harder to get the hub out as opposed to take whole assembly

 

correct me if im wrong, but didnt the 88 si also weigh less than the 91. this also has to be taken into consideration

 

Yep, CRXs got fatter every year after the 88. Same when going from HF to Si as most people know. I really want to buy an 88 HF and strip it down until it's about 1600 pounds and daily it until I get in an accident which would make it look like a pop can you just stomped on.

 

you are correct! It had stamped steel rear lower control arms, much less than the cast ones found on newer models. The 89 model was a few more pounds because of this.....then the 90-91 models were more because of the rear disk setup (Si models)

 

Seriously ... Why convert if you can just use scarebird brackets . http://scarebird.com/index.php?route...product_id=116

 

Because I prefer to change or all out. I picked up an entire DA for $100 still cheaper than those adapters. Lol
