John_01 , let's try a thought experiment: Imagine a divorced suspension with a spring motion ratio of 0.1 and a shock motion ratio of 1.0. For every 1/10th" the spring moves, the shock will move 1". We all know that shocks work by displacement per unit time via the valving, so the shock will have to be valved comparatively very soft because it is experiencing so much motion relative to the spring. This means it will be hard to do things like high-speed and low-speed digressive dampening. Maybe not impossible, but certainly harder.

Disclaimer: I am far from an expert on shocks, but I know a little bit.

Based on my calculations, I am looking at needing a 1700lb/in spring in back if I use the OEM position, which seems way extreme.
