this is an interesting point, torional stiffness goes as r^4, so 4mm makes a
difference. That said the 26mm bar works great on my car. I am not running
lowering springs, but I have put the front springs in back and stiffer fronts
(from an 80q) The bar has been on there since summer and I have yet to have a
problem. I have seen some oversteer but nothing that was too hard to control.
On wet on-ramps I can get a little neutral drift if I push it but again nothing
more. I suppose really stiff rear springs might make it more of a problem, but I
can't imagine the difference would be that great between what I am running and
standard lowering springs. (I could be wrong, does anyone have experiece with
thick bars and lowering springs?)  maybe combined with really wild alignment or
bad tires?

you can read about my set-up in a post from last summer
