First off, I know this topic has already been discussed, but i couldnt really find a clear answer for my app. I'm putting 10" fox c/o's with resi's on my 01 tacoma ext.cab (glass fenders, tube bumper. nothing super heavy) which already has camburg LT and their 8" c'o. I'm going 10" and dual rates because I noticed the 8" shocks are maxed out at full bump and droop. and they're toast. I also want a smoother ride through the little bumps n stuff so thats why i'm going dual rate. I had no idea what kind of can of worms i had opened by getting these! Pages upon pages about formulas, and some formulas contradicting others... for instance the one where you multiply the rates together, then divide by their sum, and you get a low number... but i read that two springs at the same rate will equal that rate. for instance a 600 on a 600 will always equal 600#, yet the formula i saw will say 300#. That formula also doesnt take into account the length of spring?

Long story short, I got four different recomendations on spring rates:

A friend told me to go 10" and 10" springs like 400 over 500 (he was just guessing but he races, so its an educated guess)

Kartek told me to go with a 16" 600# and a 4" helper

ORW told me to go with maybe a 14" 700# and a 8" 500#... but then he changed his mind and said go with a single 18" 600#

I would like to recycle my 14" 500# springs and maybe use an 8" 400# but i'm afraid it would be too soft?

Any advice or opinions here? It's a Daily Driver and sees the dez on weekends... Anyone with the same setup? thanks
