Front Axle how far forward

With adjustable upper and lower arms on RE drop brackets what is the limiting factor for how far forward I can set my front axle? This is with WJ steering. Is there a measuring point that is good to use?

i try to make mine so at full stuff it is centered nicely in the wheel well. but there are many other factors that come in like steering tb swaybar ect. best thing to do is cycle the suspension to find out if it hits.

pushed mine about 1" forward with the front axle swap...

no issues yet... we'll see this weekend...
