Details
NA and NB share the 4x100 bolt pattern and 54.1 mm hub, so NA wheels bolt on. The limit is brakes: the NB1 and early base NB2 use the same size front brakes as the 1994-97 NA, so 14-inch NA wheels clear, and a 1999 base NB came on 14-inch wheels from the factory. Owners on Miata.net report running 14-inch NA wheels on 1999 cars with no problems. From 2001 Mazda added larger 'Sport' brakes (on the suspension package, and by some accounts LS/SE) and made them standard in 2003; owners and a wheel guide say 14-inch wheels will not clear those calipers. Sources disagree on exactly which 2001-02 trims had the big brakes, so check the rotor size (255 mm standard vs 270 mm Sport front) before buying. NA 15-inch factory wheels were not confirmed against Sport brakes. NA wheels are +45 versus the NB's +40, so they sit 5 mm further in.
