Same path I'd like to take.
Got to be careful with which R160 axle you use though. Forgot I used a GD R160 axle while I still had the GG/GC/GM/GF track width. Had a hard time bolting the hubs back up to the lateral links. I ended up changing the track width to GD non-STi all around (IIRC 04 STi is still the same as WRX and 2.5RS/2.5i).
