i have seen a diff on ebay item 270614674873. 4.111 ratio but he is not sure if its a R180 lsd?
he has a part number on the diff which is part number 27011AA111...any idea what type of diff this is thanks?

to my knowledge no subaru came out with a R180 in 4.1:1 ratio.

I believe they were only available as 3.54, 3.9 & 4.44
