I have a 89' ED6 and was wondering what it will take to install a 90' DA9's rear disks onto it. THX!

 

yes, you'll need to source the complete rear trailing arm w/ rear disc.

it doesn't specifically have to be from a 90-93 integra DA.

any 94-00 integra DC, civic/crx EF Si, del sol Si, 99-00 civic Si rear disc trailing arm will work on your 89 civic ED6

you'll need rear disc brake hoses, drum hoses are too short. (use a 10mm flare wrench when removing the hose to prevent stripping)

once your drum-to-disc swap is complete, it's a good idea to get an alignment

do any of you guys know if a 95 Ferio rear trailing will fit a 97 EJ9 civic for the rear disc conversion?

 

Yes. All 90-01 Integra and 88-00 Civic have the same dimension trailing arms. All are interchangeable.

 

sorry to jump in ...
i recently bought a 89 civic sedan and i have a now gutted 92 integra turnd out to be a gold mine ... but reading this you say that i can take the rear assembly and it will fit my 89 civic sedan????? for the disc conversion!! do you know what else will swap?

 

attn: this is EFficial's thread, should really hit the new topic button next time

ok...i'll play:
regarding the 89 civic sedan: yes, the rear disc trailing arms will bolt on.

also from the 92 integra: take the front knuckles, calipers & b18a1 swap.

the master booster/cylinder: https://honda-tech.com/forums/suspension-brakes-54/da-booster-master-cylinder-ef-2570678/

once everything is swapped. get an alignment
