G37/370Z rear motion ratios

I measured the rear suspension to determine motion ratios.

The overall lower control arm length is 18". Pivot to spring center is 10", give or take while the pivot to damper distance is 15". This gives a motion ratio of 1.8 at the spring and 1.2 at the damper.

This is useful for those setting coil-over heights. A one inch change at wheel is 1"/1.2 at the damper and 1"/1.8 at the spring. True-type owners can ignore the spring motion ratio.
