After having a 6Speed in my car for over a year, and the matching R180 sitting on the shelf in my grage, i finaly got the parts i needed to Hybrid my axles to install it in my car...
The same parts that i had made will work to mate WRX shafts to 05+ STi inner joints so you can install a R180 diff and keep your R160 hubs.
PM me in interested in more information.

Interesting... sounds like this would've solved my friends delemma of 4.44 5MT into his 02 WRX. . . (if that's the 180 to 160 marriage application? If not, I think its a similar concept of fixing spline count differences as with EA tranny swaps into EJ rigs, no?)
What are 180's from vs. 160s? (I'm just not that into the numbers, similarly with body codes, like SF, BD, etc. . )
Are 180's from 4.44 trannies, or strictly an STi, highe HP axle?
vs 160's are those old gen axles, like EA82s or are those also early second gen, like my 95 legacy?

R160's are on everything from late 70's EA81s to brand new WRXs

R180's are only on 6 speed STI's and very few JDM 5 speed STi

the R160 has a 160mm ring gear and the R180 has a stronger 180mm ring gear.
