Ok well I picked up a set of rear celica disc brakes from a car that was being parted out. It took about 6 hours to do mainly because the two hub bolts that connect to the subframe where rusted super tight. I used air tools to get most the bolts off.

You need the following parts to do the conversion. I got my set off a Celica GT with discs option. A GTS disk setup would work too.

-Entire Rear Disc Hubs (Caliper, Rear Disc, Hub, Pads)
-All the Nuts and Bolts. Even though the existing will work I ended up smashing the shit out of the subframe bolts to get them out. PB Blaster is your friend on theses
-The Emergency Brake Lines. (The existing can work with modification but I ended up running the new disc brake lines to the E Brake. I little cleaner.
-The Brake Lines. I used these and they fit on the existing brake hard lines.
-Brake Fluid. Since the new lines will have no fluid you will need to bleed the brakes to get the air out of the lines.

Sockets/wrenchs used were the following:

21 mm to remove lugs
17 mm to remove the bottom subframe
19 mm to remove front subframe to rear discs and strut bolts
10 mm to remove emergency brake lines
10 mm open wrench to remove the brake lines

I used a 500 ft lb Ingersol Rand Air Impact wrench to remove bolts, a breaker bar plus a pipe extension (cheater bar), and a bunch of PB Blaster(very helpful for bottom)

The install itself is pretty self explanatory. Remove the rear hub assembly, brake lines, and e brake lines. Any haynes manual or chilton should show you how to do it.

Final Verdict: Braking power on all ceramic pads and cross drilled slotted rotors on this car is amazing. It stops on a dime. I can't imagine Wilwood's on this car or 2 pistons. I think that would be overkill.
