Only having an inside leg of 31" I've never needed the spacer, so forgive me if this question seems a little silly, but doesn't spacing the wheel out, mean that it is then too close to the chest for easy twirling, or does it have that vintage up close feel.
I find that the 50mm spacer gives a bit more leverage without restricting movement. I have always preferred to have the wheel relatively close and for me the straight-arm stuff increases effort too much. In many cars, once I have the seat/pedal distance perfect (which is not possible in the M3W), the wheel is too much of a stretch.
Driving ergonomics are rather complex.
