what is the actual measurement of the disco 2 ride height

Hey, can anyone tell me what the actual measurement of the standard ride height of a Disco 2 is. That is the measurement from the ground to the wheel arch, I need this as a base before I start playing around with suspension etc. Also just finished fitting a pair of custom side steps/rock sliders in steel with aluminium chequer plate coated in satin black, bit of a tricky fitup but now look smmmick.

Air suspension

or Springs?

Will depend on your tyres too. Some will have a different size slightly.
