    next time please try the search function first, you'll get a boat load of posts to reference, as this question has been asked many of times.

    I'm pretty sure you need the following, someone please correct me if I'm wrong

    1. trailing arms with disc spindles, rotors, & calipers
    2. disc brake hoses & e-brake cables
    3. disc brake prop. valve (optional, but recommended)
    4. larger master cylinder (optional, but recommended)

    1. The trailing arms on all 4th, 5th, and 6th gen civics, 2nd gen CRXs, del sols, and 2nd and 3rd gen integras are interchangeable. you could swap just the spindles, but it's really difficult due to four pesky torx bolts.
    2. get e-brake cables of similar length. for a civic, get them from an integra. for a CRX, get them from a CRX Si, or possibly a del sol VTEC.
    3,4. discs need more hydraulic pressure than drums to pruduce the same decelerative force, so upgrade your prop.valve for balanced braking. Once you do that, you're asking your master cyl. for more pressure overall, so upgrade it too. you'll probably want a 15/16". you can't simply take the integra's MC - you'll need to swap the MC and booster as one unit.

    Swapping to discs will not make your car stop more quickly. any properly adjusted system can lock all four wheels (or activate ABS), so stopping distance is limited to the quality of your tires. discs will provide substantially better fade resistance, and won't get clogged with water on rainy days. If your car pushes under braking when the fronts lock and the rears don't, you should upgrade to discs.
