Short answers by generation
Will STI R180 rear differential fit a Subaru WRX (GD/GG, 2002-2007)?
Yes, with extra parts or work (Reported, 3 sources; applies to: only with STI rear axles, hubs/knuckles and matching rear brakes). Sources agree WRX rear axles do not fit the R180, so the swap brings STI rear axles, hubs and knuckles, rear brakes that suit them and a parking-brake solution. Full answer and sources
