Naturally with out adj. tubular arms you can achieve most any caster setting you like. I`ve set them for as much as +12* caster,but that was for testing only. I don`t recomend driving around like that.

I like them around +5.5*. Much more than that makes the steering response mushy IMO and brings no additional benefits to the party. I wouldn`t recomend our adj. arms with the G mod and std. height spindles with no geometry mods though,especially at near stock ride height. The G mod brings the arms closer to the frame in droop and you may lose some travel. Now, combine them with a tall upper ball joint (not
too tall,we don`t want too much of a good thing) and lowered ride height and you`ve got some serious geometry and performance gains in addition to more + caster. The tall ball joints can also be used with other manufacturers arms with little or no modification (depending on the brand of arms) to get the same geometry gains they just weigh more and you won`t have as much adjustability.
