Does lowering 1" on coilover = 1" on actual drop?

[6carmello8]

Hi Guys,

Logically you'd think that dropping 1" on the seat spring on the coilovers translates to 1" drop on the total ride hight, but is there more to this than simple 1:1 ? I know that the geometry of the control arms may come into play here as in one inch on the seat spring may equal to more like 1.5" on the total ride height. For example, when my full suspension mountain bike shock compresses .5 an inch, the rear triangle goes up more than .5"...

Can anyone chime in here?
