I'm doing the rear disc brake swap this weekend but the guy i'm buying everything from is giving me the whole suspension. Both front and rear. Can i use the front knuckles off the integra on my civic? I was told it will bolt right up but i havn't found anybody that has done this. Will the brake boosters swap out or will i just need to change the master cylinder?

 

The front knuckles and brake assembly will bolt onto your civic. I have it on my CRX. The only thing that you will have to do after installing it is get an alignment. The Teg knuckles throw it off and that's why people tell you to get the 91 Civic Ex ones, but they are harder to find than the Teg's.

 

Do a search.

Honda OEM is always the proper option, and the only place that size brakes were available for an EF is either the JDM SiR, US EX sedan, or EDM 1.6VT models. These parts bolt on (but only the knuckles/brakes, not the upper or lower control arms). I have had experience with almost every possible combination on my daily driver hatch, and my conclusion after measuring a number of different parts and installing them, you can only use the knuckle/hub assembly from the appropriate models to retain the proper suspension geometry. That's not to say that other combonations won't work, just not properly. And even with a camber kit installed, you are only compensating for poor geometry somewhere if you are using the DA parts.
As for the rears, on honda's, it is usually best to retain your factory trailing arm and just add the brake to the stock arms. Here again many combo's will work, just nothing properly. DA's arms will give you more positive off set in the rear, and the lower control arms will give you negative camber.
Many people have opinions, because as I stated, many combo's will "work". Just do the math and measure some parts and the picture will instantly become clear that only certain parts will retain factory geometry.

 

So that means my '92 hubs on a '90 hatch was a bad idea? How would I run the suspension I was planning with the '91 ex's? I ordered Tein's with the EDFC. I wanted to see what they where like the I ran into '92 Si hubs and LCA's for cheap.

 

me too. They guy is giving me both the front and rear suspension and the brakes plus the center console out of his '92 teg for 100 bucks.
