f*ck...how many times do I have to say this shit before someone actually listens to me? God this board pisses me off sometimes.

It doesnt matter what year integra you get them off of...91-01 all work - but for simplicities sake 94-01 is what you want becuase of the bushing size.
As long as you relocate your sensors that are on the civic, you don't even need the integra's abs units. And before you ask: All trailing arms are IDENTICAL. Meaning that your civic parts will bolt right up, no problem.

The em1 si was not offered with abs, in the states. So if you want to keep abs you will need rear hubs (not necessarily entire rear sets) from a car that had abs equipped.
Del Sol vtecs came with that stock (I am positive about the 96-97, I only assume on the 93-95's)

But like I already said, keep it simple, if youre confused. Just look for integra rear arms and brakes. They all had abs, so there is no doubt that you can retain it. (Though, if your civic does have abs...it should already have rear disc).

OH, and for those that think that gsr front calipers are special, they only LOOK different because the ls and gs use a different style of pad retainer clip. The piston size between all integras is THE SAME. I don't care if you listen to me...I know Im right.
