I installed this kit in my 91 coupe back in March. I wanted to do everything at once so I also installed all new hard brake lines, 93 Cobra booster, stainless steel soft lines, and Hawk HPS ceramic pads. The car stops like a dream now. I didn't expect it to make such a dramatic difference but it was a huge improvement.
Let me know if you have any specific questions about it, but one thing I remember about the rears were that the dust shields would not mount properly without rubbing against the rotors. I just left them off rather than try to make it work.
The hard brake lines also required more checking for leaks and tightening than I expected so make sure you check and double check them for leaks before considering it done. I have some pics, just let me know and I'd be glad to share.
