75w90NS for the transmission, since it needs a little more specific oil fro the sychros to work best. the same fluid (so you only have to buy one type of fluid...but it only works for an open diff), or regular 75w90 for the rear

Race shops usually carry redline. You can also get it from www.summitracing.com or www.subaruparts.com and lots of other places.

I like amsoil svo 75w-140 for my soob diffs. A little extra edge of protection. I wonder if maybe your previous post about some soob diffs getting chewed up is due to inadequate lube protection? Some pickup truck makers and others have come out with tsb's saying to replace the factory fill 75w-90 with a 75w-140.

i don't think so because it's only "newer" vehicles from what i'm seeing, which isn't much since front diffs don't blow that often. i've seen quite a few "newer" EJ stuff say 1996-2002 with blown front diffs, a couple last year. i actually can't recall seeing any pre-1995 with blown front diffs, which is even more odd by the fact that an older car with a blown diff is more likely to hit the selling block and be more visible than a newer vehicle.
