So was just visually looking at my zilla front end vs. my yfz.  the zilla tie rods are at a lower angle to the a arms as opposed to the yfz.  The yfz is almost perfect as far as a arm / tie rods being at the same angle.
The zilla has a signifigant drop in the placement of the inner tie rod ends at the steering stem location.  I have been nagging my buddy to get his kfx out of my shed for months now and now I want it back! LOL
Im pulling a lower ball joint bolt this weekend to take to a local hardware supply house to have .375 spacers made/ordered and a longer bolt as Iceracer had suggested to get -2 deg. camber.  I usually run -4 deg. on my yfz.  Ill put the shims in under the front inner tie rod ends and see what ive got.
I prefer more neg camber for reaction and steering precision, but run a cross country style caster angle for higher speed stability. Just seems to fit my riding style.
Im gonna keep playing with some spacer combos this winter to see what actually works and what dosent, but i have to say that the frame and a arm geo on the zilla is not the best starting point.  Still better than the 250 tho.
