Hi

I`m trying to find out some info on Subaru diff`s. I`m building a Birkin (seven sportscar) which has the option for using a Subaru Impreza rear diff. I`m looking for a LSD which I ssume they all were. The information I require is as follows:

Differences in diffs over the Impreza`s life, which were good etc
Diff ratios available
Weight of diff
Prices of new or second hand units
Good places to buy the above (in Northern Ireland if possible)

Any info would be really appreciated.

Thanks

Simon
