I have the Rubicon takeoff parts and I've been doing research on the installation. What I don't understand is why the LCA needs to change if you only change springs and shocks. I understand what caster is and I understand how the geometry changes when you lift the suspensioni, but what I don't understand is how the Rubicon gets away with the same LCA as the sport when it is effectively lifted the same amount. IOW why doesn't the Rubicon require a different LCA with its stock springs and shocks? Take them off of one frame, put them on an identical frame without the decal on the hood, and the geometry is different? Is there a difference in the mounting points on the axle that makes the difference?
