Check out the FAQ section of this forum for all of this info. There are also lots of good DIY write ups around if you google it.

Basically you need the rear brakes off of a 99-00 si or a 94+ Integra. If I were you I would just swap the whole rear trailing arm over from your donor. You will need to use your Civic LCA's and compensator arms (I think that's what they are called. The other two arms that attach to the car). You will need the brake lines and e-brake cables from said donor car as well. Most people say to get si e-brake cables because they fit perfectly, but I had no troubles fitting the Integra ones in my hatchback. I think you will need the prop valve from an si as well for your coupe, but I'm not 100% sure about that.

After that, pretty much all you do is unbolt everything off of your car (trailing arm assembly, e-brake cables, brake lines, etc), remove it, and replace it with the parts from your donor car. It's not that hard, just takes some time. I did mine by myself in a couple of days. I was working slow though. It would definitely be easier with a friend there to help you position the new trailing arm assembly as you bolt it up. Once everything is bolted up, you will need to bleed your brakes to get all of the air out. This may take awhile, but make sure you do a thorough job or your pedal will be soft as hell! Also check your brake pedal height and adjust that, if needed.

I think that's about it. It's pretty easy as long as you are somewhat mechanically inclined. Oh you might need a can of PB blaster for some stubborn bolts. I used that on some of mine and did the whole job with basic hand tools. Have fun.
