I need to know if im suppose to use these parts of the da on the crx while
doing the front and back brake conversion.

The hand brake cables? They seem to be a lot longer

The lower control arms. Front and back.

And any other parts im suppose to keep of the crx, or da?

 

E brake cables must come from DA they fit...i did it to my car...LCA i have the stock CRX ones...but i believe DA even Stock ITRs will fit...good luck...

 

DA rear LCA will fit but are not the same and not recommended.

basically, dont use any control arms from the DA on a CRX. just use the knuckles and trailing arms.

 

Would ef cables not work on my ef with the da brakes?

I know somebodies tried this and either has succeded or failed.

And the extra piecies on the end of the trailing arm,
And the part that attaches the brakes to the frame right behind
the suspension?

Are those supposed to be ef parts?

 

use DA cables,
ED compensator arms (dogbone looking pieces)
ED LCA's

 

what model is the ed?

 

ED=USA
EF=JDM
