spring height?

[dgbnova#1]

I have a load of rear lowering springs all different heights when off the car, is there a way of knowing what drop they are without putting them on the car or the standard measurements this is calculated from so if I have to fit them I can work out the drop for each pair. Any info please

I would just try them on the car as its quick enough to swap springs just dont fully tighten the shock nut as the weight of the car will hold them in

I would mate but just no time and my gsi of the road and my other car is a shell so gona be high anyway and I want to shift the ones I don't want probably 6 spair pairs of rears there
