    Just got a 2/1 lift and alignment check. A bit skeptical of my numbers, doesn't really come close to any of the numbers I see on here, but rate my numbers lol

    All your numbers are within the stated spec from Toyota. If you wanted something different you should have told the alignment people. Lift is kinda irrelevant to alignment numbers, it’s changing wheels / tire size that you may want to think about using something different / moving away from spec.

    two things. your setup isn't challenging obviously. but those little tires are fairly sensitive to these uneven numbers.

    it kind of looks like they were struggling to get enough caster, and also that they did toe before finalizing camber (should be camber/caster first then toe). anyway, your front camber numbers are likely causing the drift, because the uneven lean and therefore weighting on the treads left-front vs. right-front are allowing the right-front to grab more and pull a bit. the camber should be even L & R, and the correct zone with your setup is somewhere in the range of -0.5 to 0.0.

    the caster is possibly a bit of an issue but not so much about the drift. if you can dial in camber and toe to be even (your toe is fine btw) and if you are still having driveability issues, then the next stop is to install aftermarket upper control arms to increase and adjust your caster. the difference left to right isn't an issue (and it looks like they may be adding more caster to the right-front possibly to compensate for the right drift). but if it feels choppy, restless, or generally unsmooth or unstable on the highway in terms of steering, more caster will fix it. most around here focus on caster as a clearance factor when installing larger tires, but it affects steering and handling a lot.

    at this point, however, i would shoot for
    - even camber on the fronts: -0.5 to 0.0
    - max caster (at least 2.5deg if they can get it) but not more than 0.5deg difference L to R
    - keep your current toe (0.05 toe-in is OE setting)
