If I remember right if you order any new hub from Mazdacomp it will be the same number for the 89-93 and 94-97. When I bought my car before I started to build it it had the bigger na brakes. I have since gottent he proper brackets and calipers. Actually I bought a whole knuckle for the rt and lft. I just removed the caliper and brakets and installed the proper ones. I have not noticed any problems so far. So you should not any issues.

Rear calipers are the same, front calipers are different. Brackets are different between 90-93 and 94-97. Hubs/knuckles will swap from 90-97 no problem, mechanically or legally, though the rear studs are different size. Info overload?

Front brakes: You must have the correct year(90-93 vs. 94+) pads, rotors, calipers and brackets. The spindles, hubs and lugs are all the same.
Rear: Calipers are all the same 90-05. Caliper brackets, pads and rotors are different 90-93 vs 94+. 90-97 rear uprights are all the same, as are the wheel bearings. 99+ uprights are different, but the bearings are the same. 99+ rear upright give a 10mm wider track and are not legal because of this.
90-93 rear hubs use a smaller hole for the studs than 94-05. Other than that they are interchangable. All new hubs are th 94+ design.
Hope that all helps
