front rotors

Did Toyota upgrade the brakes from 91 to 92 on the turbo models? I have some drilled and slotted rotors for the front that I am interested in, and it says it is for the 92-95 models. Will they fit on my 91 turbo?

All those Mr2's and no one knows!?

Late 92s+ had a larger front brake system.
91's and early 92s had a smaller rotor.
