Is there some kind of formula out there or way of figuring out what leaf spring rate you need? There's got to be a way to do it without just shooting from the hip, buying springs, throwing them in, calling it a day. My machine weighed 3900 lbs empty before I built the rear bumper/tire carrier. This weekend I'm going to put my front bumper/winch on and scale it again. Right now my rear springs are IRO 3.5 inch 7 leaf packs at 185 lbs. The optional 8th spring will take it to 215. Front coils are PAC 4 inch 250 lbs. I'd like this thing balanced as correct as possible. TIA
