same hubs on 04. Don't forget interior add-ons. Diff gauge cluster, red stitching, blue carpet, blue seats, shifter trim.Different cars. Important differences are: STi has the 6-speed, better front and rear differentials and fancy center differential that even lets driver control it, bunch of stiffer bushings, wider track, bigger and stronger hubs (with different bolt pattern), Brembo brakes, stronger inverted struts with stiffer springs, larger turbo and intercooler. And, most importantly, the ginormous wing.
