Do a search on corral, gotta be a ton of threads on this...
I did the 95 stuff in the front and the northracecars kit in the back, all is good stuff that wont burn a huge hole in the wallet...
good luck!
I've got a rear disc setup with everything you need, except its got 1 bad caliper so that would need to be replaced.
Brackets, bolts, rotors, blah blah blah...
Look on corral for Matt90GT conversion, or a google search for the same name....
