Can anyone tell me what the diff ratio is in a 2003 WRX STI (Aust. delivered)?

I'm thinking it's 3.9:1

I think it was 3.9 as well but if you have the serial number of the Box Brett has a listing of what ratio coincided with that number

3.9 as you thought. Buy the diff and worry about the shafts later.

I was outbid. Ended up selling for $405 plus freight would have been $80 so I let it go. I am a fair way off needing an R180 anyway. When I do step up, I think I will get shafts made with Porsche flanges so I can run 904 or even 934 CVs.
