The SPC arms are not hard to work with unless the factory suspension is messed up. I had them on my 4th gen and ran them until my 35's were just a bit too much for them.

5.5° is far more caster than you need or want unless you're trying to run 34's or larger. I wouldn't go too much higher than 4° as that seems to be a good sweet spot when balanced with a fairly neutral and/or slightly negative camber for wider/larger off-road tires. Additionally a little extra toe-in can help with chunkier tires, there is such thing as going too high; at which point the vehicle will track too well and follow every imperfection in the road and feel like almost like it's wandering.

I wouldn't trust any place that can't or won't provide all your measurements. I will adjust specifications in our machine for our lifted customers so their custom specifications don't show up "Red/Out of Spec," but they always get their before and after measurements with a note that it was adjusted for "lifted specs."

Post Note- tire shape and pressure are also very important.
