caster mod by crossmember relocation.

[scum1]

I am about ready to section my crossmember and during the process I am goin to remove the upper coil pocket of the crossmember, and fabricate a new upper bag plate, as well as move the crossmember forward 1", to better align the wheels in the wheel well.

as i was thinking about this, i will be in a unique position to be able to leave the upper control arm in its stock location (fore/aft wise), and move the crossmember (and subsequently) the lower control arm forward towards the front..

I have read various threads on caster mods... doing what i suggested above would no doubt increase the caster right? im literally moving the whole control arm forward an inch while the upper stays where it was.

Has anyone done this before? is 1" going to yield too much caster increase...to be honest im not sure how to even measure caster. other than tell if both wheels are the same from a point on the lca to a point on the frame.

while i was looking at everything it dawned on me that could be fairly easy to do while im fabbing this all up..if im picturing it right.
