*rough* coilover spring rates..?

[Kinserin]

I know the preferred spring rates for a rig are determined via actual weights about the rig, but I'm unable to actually determine everything involved to fully tune the rates I need for my front coilovers. Just guessing by what some decent coil spring rates were I'm figuring I need a 350lb-400lb main and something like a 300 tender? Or is that too stiff/soft..

Again, I apologize in advance for being able to provide virtually no information other than my Ex is a 91 with a 44 front, and its got a 347 pushing it.. I'd prefer a softer ride over a more streetable/stiffer ride if that helps.

Thanks in advance if anyone is able to sort of point in the right direction other than a spring rate calculator

Mine are 250/350. It is really nice and soft.

Sounds good, I'll need slightly stiffer springs compared to a stock body'd explorer because of all my extra weight, so I can at least go off your numbers.

Much appreciated!
