Spring rates

Alright I have on my flame retardent "stig" racing suit so here's the question.
I need a good starting point for coilovers springs. I have a cj7 stock up front with winch and tube fenders.4.0 motor, and 2 seats. Back halved with minimal tubing in rear. Stock frame but reinforced and smoothed. I'm running air shocks in the rear and coilovers in the front, and looking for a good starting point for coils on 16" FOAs. Typical terrain will be crawling and class 5 trails, so under 5 mph. Not sure of weight of front, rear, or otherwise and don't have scale access.
So boys let's play well with others and be nice and point me in the right direction.

put bottom springs on it, measure how much they compress and multiply by the rate to get your corner sprung weights then figure out which upper spring you need to obtain the overall rate that delivers the desired spring frequency.

weighing at the wheels is not very usefull.

Search for "spring frequency" in Gen4x4 and make sure your calculator has fresh batteries.

You have to know weight first.....i have a set if 14" 140# springs that I use to get corner weights. Then the fun begins picking rates and lengths that will give you the ride height you want and ride quality you need.
