Or, is it already stiffer using the outer hole? I'm not planning on going inner hole yet.

Doing one thing at a time. With an LSD coming in next week, I'll start with stiffer front bar and LSD, and go from there. I can remove the rear bar or install the 18mm bar, but will leave that for last resort. The car rotates so well and handles great that I don't want to mess with a too much of a good thing.
I can't answer the question on how it compares to an "M" bar, but I have the H&R on my 3.0si. I tried the rear holes and that was a bit too soft, and the two forward gave too much understeer. Currently I'm running one forward and one rear which is the middle stiffness setting and that's seemed to be about right.
