You can upgrade to the 96-98 brakes, or even the ones from the cobra, but I would not go using another car's calipers on your stang. I guess if you have all of the brackets and rotors and everything, theoretically you could swap it over, but why? Go to your local parts store, order some calipers and rotors for a Cobra of the same year, then turn in the cores and they'll never know, seriously, it's shady but whatever, my brother just upgraded the brakes on his 240SX to the 300ZX Turbo brakes doing the same thing.
