On second thought, I should have added poly bushings on the front bar and fabricated stiffer endlinks.
When I went from a 1" front bar to a 1-1/8" bar in the Miata, I also went to beefier endlinks from Racing Beat. That transformed the car into being much more controllable and really planted the rear.
Having a better anti-roll system in the front would have made similar benefits, I'd bet.
My rule of thumb is that work on one end of the car either frees or tightens up the other. So if you have too much roll in the rear, you use the front to tighten it back down.
