what size rear sway bar matches up with eibach lowering springs all around coupled with tokico blues (roughly 240 front spring stiffness?) ..as it is w/stock sway bars the Probes cornering/road handling performance is dramatically improved over stock springs/struts..

Mostly what sees to be happening with swapping the springs only is that the front tires benefit more from the slightly reduced amount of roll than the rears do. It looks like the Tokico springs not only maintain similar "flat ride" behavior - they also do not shift the front/rear distribution of lateral load transfer much either, both setups being about 61/39 (with 25.4 mm front and 12 mm rear bars assumed). Moving the rear bar size up by 4 mm makes the lateral load transfer distribution about 57/43. Definitely "looser", or at least "less push". Just for reference (and as a disclaimer, not intended as a general recommendation), that 22 mm piece would put the LLTD at 48/52.

Most design philosophies want the LLTD to be within a few percent of the weight distribution, with the front LLTD normally being a few points higher than the front weight % to help ensure a little at-the-limit understeer when car usage and driver capabilities are unknown. For example, some experienced autocrossers prefer a setup that's far too "loose" for a newbie driver to be using on the street.

Late edit - the bar sizes are from a 626. Slightly different PGT bar sizes will shift the specific numbers around a little, but won't change them relative to each other much.

Again, it's all personal preference.............but I personally wouldn't recommend any bigger than 16mm regardless of your objective. Even hardcore racers would be better off using stiffer rear springs instead of using a really thick bar. Thick swaybars sacrifice traction over bumpy corners.
