If you're still in need and in/around SF, I've got a torque wrench that I used to use to switch from snows/summers that I no longer need (so long, fun car...). Willing to lend, or permanently exchange for beer. It's about two feet long, so lots of leverage, and can be set up to 140 NM, I think (Audi spec was 92 NM, I think Subaru is in the same range). I've got the extra-deep socket attachment to get down into the rim as well, if that's required.
