Recommendations for Reducing Body Roll?

Again, my thinking may be way off. Just trying to clarify.

Also, in theory all of this makes perfect sense but what would be the best thickness for the front sway bar to coincide with my existing 19MM TRD rear sway bar? Tanabe offers 23MM and it looks like Ultra offers 25MM. Any others that I'm missing?

It does not fix the root problem, lack of spring rate. You can toss good money after bad putting bandaids on there, big front bar, braces, but none of them are a replacement for a proper shock and spring package.
