A 5 speed D/R and an EA81 are all you need, stay off the skinny pedal and its perfect, you wont break axles burn clutches or anything, My Wheeler has been perfect and I have no chain Reduction hubs or any thing special.
Try Wheeling it on some trails and stay out of the watery mud lakes. this is a crazy idea, If monstaru wont try it, it shouldnt be done, Listen to him if anything, he is a very good voice of reason, just read what he wrote two times and you'll get the Idea that, no you shouldnt do this, or even bother with it. The worst part is you keep going about your thread like a bad singer on American Idol, You just keep singing right over the judges......... Stop and read what some of the People who understand how Subaru's function, They have good insite on this, And that is Money Welders, Time, Knowledge and dont do it. I'm not puting you down but this is tread 603 of Crazy Idea time from you.....
