School me on Alignment and UCAs

[FamousAv8er]

Im going to be installing 5100s all around on my daily driver this next weekend at 2.5/1.5. I'm going to stick with the stock UCAs and stock Nitto TG G2s 265/70/17. I've never questioned an alignment I've received but I would like to be more informed. After doing some research Ive learned the 3 main points to adjusting alignment and how UCAs can help a lifted vehicle gain more caster for a better alignment. What I'm still wanting to know is;

With the described setup, what sort of numbers am I wanting to see for my alignment to be considered "in-spec"?

What kind of numbers are the goal to a factory or better drive from the described setup?

If I'm not able to reach the desired alignment specs, what UCAs should I consider for daily driver application (low to no maint, high reliability)?

UCA for best alignment

Get the UCA. It's the best way to achieve proper camber. The JBA with a ball joint is goo. The ICON tubular UCA with their new Delta Joint is sealed and may be the best option for low maintenance and reliability. Dirt King makes a nice looking UCA. These are my 3 favorites. I have the ICON.

I agree, just get the upper control arms. Better caster for highway handling.

Every vehicle is different but here's my experience from stock to now.

Bone stock with an alignment from Toyota:
I complained with a pull to the right and it still pulled to the right possibly due to that caster set up. I didn't know any better at the time. I just know the paper they handed me said camber, caster, and toe were all out of alignment and they fixed it.

Different shop with 2.5" in the front (possibly closer to 3") with stock UCA:

I actually took it back to them when I had my current set up now, and they didn't know how to approach it. They gave me almost 6 degrees of caster on one side. I complained the next day and they gave me my money back.

Went to one alignment shop between this time and they got it handling nice. Still had a pull to the right. Tolerable though.

Current set up with slightly over 3" of lift:
Best handling yet but I still have a pull to the right (gets straighter at 40psi+ in the tires) but after 2 alignments from this shop and the one above this shop, both reputable, I more than likely have a tire pull.
