how to custom long arm susp.

[mossyoaktj]

so ive been pondering the idea of fabbing up my own LA for the tj rather than dumping the boat loads of cash to buy one. the welding and building is the easy part, but the geometry is what gets me. i want to build something that perorms well offroad and behaves on road.

ive heard of the calculator but never used it. what measurments does the calculator give you? im pretty much lost when it comes to non labor part of the build. ive looked at a few write ups, but those were mostly about how they built brackets and the arms. nothing really explaining on deciding mounting locations and what not. im still researching this before i start in a few months, trying to get everything together that i will need for the build and learn as much as i can going into it. any help would be greatly appreciated.
