Anyone here gone through a process of checking suspension springs?

Book says

Unloaded length ~ (approximately) 255mm

[So my springs seem to fit that specification]

Length when loaded with 435 +/- 12 kg => 177mm

[Why 435kg? I guess that must be the expected weight of the front end of the car?]

Length when fully compressed => max 113mm

[I´ve got an expensive internal spring compressor for a Mercedes that would enable me to do this but really it seems a bit OTT even for me]

Loading required for compression of 1cm Measured within spring range 155 - 200mm => 59 +/- 2kg

[Hmmmm - how would I...]

Useful information that is quite hard to use in practice...

#########

So the point of this post - is there an official ride height specification for the PV?

I can´t find that even in the section for tracking adjustments - many vehicle manufacturers specify ride height before you start messing about with castor camber and toe...
