Coilover Conversion

[DeanMLFlame]

I'm wanting to get rid of the leaf springs on my '91 Ranger XLT and replace them with a triangulated 4 link and coilovers. I want to make a streetable drag truck for weekend fun. My question is what spring rate or load rate would be appropriate for this. I would like a fair amount of squat on the launchs. I've looked for calculators but they only tell me how to find spring rate with dimensions of the coil. Anyone help me?​

what you asking for/about, is more about the geometry of the link system its self.

i just wanna know what would be the right RANGE of spring rate so i can have good lauchs but still keep to truck streetable
