omni-difference between sport and street coilovers

Hi i tried searching, but only found threads on how great omni’s were wether than actually saying the difference between the sport and street options. Well whats the difference?

I believe the difference is the spring rate,

street: 10k front, 8k rear

sport: 12k front, 10k rear

somebody correct me if im wrong.

But dont they offer to set your spring rate?

yea ur right about the spring rates, but i just wanna know how soft the streets are…thinking about gettin the streets…will they sag? i thread jacking? hope not…
