If you look at the chart that shows the ride height, there are several variances depending on car and options. Those heights vary from 7-8-9 inches etc... Those are taken from the rocker panel.

Each car is a little different in the instruction manual but you first measure inward from a fixed point, down the rocker panel to find the location the measurement is taken from. That fixed point could be the centerline of the wheel or at the edge of the rocker panel itself. The same procedure is done at the front of the rocker and at the rear of the rocker.

It's important to find that fixed point the measurement is taken from on the rocker for an accurate measurement, because moving up and down the rocker any distance will change that measurement.

Hope that makes sense.
