Lowering suspension geometry

If I throw a set of coil springs that will drop it about 4", from in my brain it shouldn't effect the front except for pushing the tires forward correct? Since it doesn't have to worry about pinions angles you wouldn't have to adjust for that? 

 

I might throw some adjustable short arms to keep the tires in the center of the wheel well for looks and to help it from rubbing.

it'll affect it somewhat, but might still be within specs.

In theory, extreme lowering of the MJ's suspension (4-linked straight axle) could affect the same parameters; incorrect caster (which is also your pinion angle on a 4x4), the axle could get off-centered du to the track bar now being the incorrect length and wheels might get off center in the fenders. The stock suspension gets the arms pretty much parallel, but either lifting or lowering would pull the axle back, although I don't know if the control arm brackets will let you go low enough to get into those troubles.

I am going to lower it and then see how far off the castor is and see where the wheels end up in the wheel well. I am mostly worried the castor will be off. Lowering it should give me a little bit more castor, which wouldn't be terrible I think

 

What is the stock castor angle? 7.5°?
