I've got rear drums, and am looking to goto discs. Yes, I know it isn't going to make an improvement, I am looking for it being easier to work on.

1. Are DA RTA's the exact same as a EF RTA's?
2. Does it take the same RTA bushing that the drum RTA's uses?
3. Also, will the same brake lines work?
4. Which cars can I get the 4040 prop valve out of?
5. With rear discs and Spoon ITR calipers up front, which MC should I be running for track only use?
6. Are the 90-91 EX's the only cars with the desirable front knuckles or do the DA's have them as well?

yes, the 2 arms are the same in geometry. *but* there are a couple differances. the compensator arms are differant lengths, the ta bushing is a differant diameter and i think the upper control arm may be a differant length.
also, i do remember from back in the day that theres a way to use drum TA's and put the disc brakes on them. a search will clarify all of this.

you will need differant brake lines (for crx si or da integra.)

largest MC u can run w/o changing the booster is the ef ex 15/16ths. theres a prelude one thats 15/16ths with the same blot pattern as well.
da knuckles will change the suspension geometry up front. you can get the fastbrakes 11" kit with itr/spoon fitment.

1. Are DA RTA's the exact same as a EF RTA's? not exact but bolt up perfect
2. Does it take the same RTA bushing that the drum RTA's uses? no
3. Also, will the same brake lines work? no
4. Which cars can I get the 4040 prop valve out of? da integra ex ef.
5. With rear discs and Spoon ITR calipers up front, which MC should I be running for track only use? 15/16 or if you want to make new lines put a 1inch ITR
6. Are the 90-91 EX's the only cars with the desirable front knuckles or do the DA's have them as well? i run da and they are fine. ex is slightly better

the da trailing arms will bolt up but it will make the rear a little wider it should be ok as long as you dont have very offset wheels

 

EF 4dr EX does NOT have a 4040. it has a 3540. only 90-93 integra non abs has 4040.

dont ask me what the difference is, I DONT KNOW. (no one else does either).

but EX's did NOT come with rear discs tho, just drums.

I have to agree with him on this. When I did mine from the drum to disc the DA trailing arms did cause a slight ever so slight rub on both sides that I did not get with the stock trailing arms, same tires and wheels. It can be remedied with either fender rolling (what I did), raising the car, or offset. It really isn't a huge difference though.

 

I beleive it was 15mm more offset on both sides. Not a big deal if you have the clearance.

OR get CRX Si discs if you are that worried..

Yes, another one agreeing with this statement. In my case however it has caused me a TON of headaches. Trying to set my compression in my dampers to compensate so it DOSENT rub (and Im only running a 6 inch MR5 wheel) when I have a passenger around hard cornering has been a pain in the ***.

Here is my question that may help you out as well. If one has done the DA rear swap and used the DA rear trailing arm, can you then swap over to the SI rear arm and will that correct my problem (and possibly his in the future)? Thanks!

 

i ended up switching back to stock trailing arms and just bolted up the da disk brake parts along with the da hub and spindle mine didnt rub with 15x7 +35 wheels with rolled fenders

 

So if I get 90-91 CRX Si RTA's, I should be good to use everything still? I just bought all spherical stuff for the rear, and it would be a PITA to now have to buy all new stuff.

 

yes you will be able to use everything

same issue here.. with 15x7 +42 offset.. i just took out the baseball bat and did a little fender rolling so it doesnt rub now. the extra offset does make the wheels sit nice and flush though

 

learn something new every day. that makes sence.

 

I put full DA suspension on my Rex and it works just nicely.

 

Same here, got full teg suspension and even did the type-r/prelude 11.1" front setup. The DA arms do cause the wheel to stick out a tiny bit more, and u can use ef arms with da brake parts with no problems. it all comes down to the offset of the rim, and how far u can roll the fender oh and to answer other ?'s the bushings are diffrent sizes and the the master cyl from 89 prelude lxi fits without having to use a teg booster and is 15/16ths u can also use ex four door one.

 

Well I found a EF Civic EX today and got its MC and Booster

 

why didnt you get the knuckles???

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!

 

Because someone beat me to it. I was pretty disappointed. But I'm doing the Fastbrakes setup up front anyway, but I would have at least gotten them to sell.

That sucks. Brian at Fastbrakes has good stuff.
