Assuming nothing else changes, how much lift can one expect to lose by relocating the factory upper rear spring perches to the center of the frame arch (so that the springs sit straight)? It is something I need to do to get my bumpstops in alignment since I now have a rotated axle and sye. I ask because it sounds like it could be opportunity to run a spring with a longer free length. Thanks in advance.

I didn't have any noticeable loss when I relocated mine. @jjvw lost some lift when he did his, but I believe it's because he trimmed down the mount.
 
I thought moving the upper perches (and straightening the springs) increased the lift?
