Correct Shock length

[SteveC]

I'm trying to work out the correct shock length after my recent lift. The stroke length of my current shocks are front - 8.25" & rear - 7.88". Currently at rest the front shocks have 5.5" travel up and therefore only 2.3" drop. The rear are much the same. Would it not be better to have the shocks half way extended at rest? I would think that 2.3" down travel is not enough. what do you think?
