Conceptually, C-HR suspension might be applicable to the K chassis too. Guessing from compatibility charts for tein's aftermarket, the c-hr struts are different somehow but apparently the mating and mounting dimensions are similar/ the same.
There are raising and lowering springs avail for c-hr and struts available (the teins) and there are coilovers available from a german company titled STsuspensions (KW production and designed for the 1.2l and 2.0HV global / German models). The USDM c-hr is listed at 3300 lbs and is softly sprung and lightly damped in my opinion, with front weight bias.
I have a set of factory struts and springs for c-hr in my garage i can measure. I also have the STsuspensions coils in my garage. I think I'm going to sell the C-HR so this stuff would be avail, I'll post about it later there is a lot going on
i might have spring rates for the coils but i don't know what the dampers that they pair with are like
