I've now noticed several suspension trends for the miata and wonder what you all think of them.

It seems that many road racers and auto crossers will still go the traditional route of choosing spring rates that will be as soft as possible so as to use the maximum of suspension travel and then stagger the spring rates front to rear to tune for a neutral mid-corner drift... then using minimal bars to limit the body lean to no more than about 2 degrees. As the cornering speeds are much higher on a roadtrack, a typical roadracing spring stagger is approximately 700# front 325# rear, then also using big 26 mm front and 24mm rear swaybars , while an autocrossing set-up might be more like 400# front 200# rear... with smaller front to rear bars.

However, some street and autocrossing miatas are running something quite different... Nearly equally matched spring rates front and rear,(375#front and 350# rear) with a really big front bar (like the Racing Beat bar) and then almost no rear bar. I suppose that they are more interested in lightening fast turn-in rather than total traction? What's your impression on how these cars drive?
