Oh yeah, that camber and axle angles look just fine. Nothing to be improved on there. Oh except for terrible positive camber, and 30+ degree angles on those axles. They are bottomed against the edge of the cup! FWIW, the problem breaking axles is on uptravel, when the wheel has lots of weight and traction. At droop like shown, there is not really any traction to transfer power so that's not where the breaky breaky happens. And the axle shafts hang "ungaurded" just asking to be backed into rocks on rough terrain. Been there, done that. Thanks for posting pics that so beautifully illustrate all the problematic stuff that happens with long travel EA81 set-ups.
I see too that your lift blocks use all right angles, with no diagonal bracing, and especially doesn't look like your torsion tube is cross braced. You will have issues with that soon enough,. If you don't your not wheeling like I wheel my car. MY EA81 is not my DD. And I didn't build it to look cool. I built it to wheel. Been doin so for years now. I know that of which I speak.
As for the shock mounts.......I've got that covered......continue watching the progress of this thread and you will see. I have previously reinforced those mount points, tie them into the body rail below and above. I've got Long travel Bilsteins punched 3" up into the trunk. mounts are brace in a triangulated pattern, and tied together with a crossbar in the trunk that serves as a hi-lift jack mount Believe me, the mounting area is strong enough and built for a long travel already.
I would ask that if you want to further talk about EA81 rear suspension and how YOU think it should be setup......Please start a thread. Your car is an awesome build. And for fun, most of the time, the EA81 set-up you've got is great.....your's is about as good as it can get......but that's the point.....it's as good as it can be, and I am ready for better.....
I'm sure the OP would appreciate keeping this one focused on his Outback projects. One or 2 post with a comparative point is fine, but we are getting now into thread jack territory. I only posted in here becasue I am modifying the same type of set up as him.
