My guess is that it would work fine as long as you could adapt the electrical signals (control/sensor). I believe the front and rear calipers were both larger in the mk4, so the proportion is likely still quite close. Worst case, you could install a brake bias adjuster like this one:

...of course, you could always take it a step further, and upgrade the MKIII with MKIV calipers&rotors too!

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
