this is why i'm running a bigger wheel spacer on the front then the back.....that .25" difference makes all the difference. in more ways then oneWell its apparent its not a linear ratio. But it sounds like the higher you go the greater the ratio and that may be due to a loss/gain of leverage as the lca angle increases/decreases. May also be good to factor in wheel offset, as it increases more leverage is applied on the spring upward lessening the lift. Regardless Bad Dads 1.6 multiplier is a spot on rule of thumb.
Ok going back in my hole now
