Alignment Specs after SPC Ucas

So after installing a 3” lift and SPC ucas this is my alignment specs. I do not know much about this as I’m pretty new into the off-road scene. How do these numbers look to y’all? And recommendations. Also my front passenger side tire is not poking out as much as the other tires. Running -12 offset.

 

SPC’s my numbers. Did you specify what numbers you wanted? Caster should be 3.0 - 4 IMO. My truck drives Great

 

I have a 3" lift up front and SPC UCAs. Camber and toe are close to zero, like yours. My caster is 2.1 driver/2.9 passenger, which drives just fine in my opinion. I would see if the shop could get your caster back up to where it was (~2.5), while keeping your camber and toe within specs.

 

You should go back for another adjustment, or take it somewhere else, imo. Your front tires should have the same poke. That's just basic.
I like more caster to keep my larger than stock tires from rubbing, but I also like the road feel of more caster. You'll have to decide what feels best for you. It might be perfect where it is if you're not rubbing.
If you want something different than what they did, keep in mind that most alignment techs are only trained to get the vehicle in spec. You have to talk to the tech and tell him what you want, so he knows not to just do it by the book. Be specific, like "keep camber and toe in spec, but increase my caster to __", and "I'm ok with the caster not being in spec".
The fact that you have SPC makes it more complicated. They are fantastic and I love mine, but most alignment techs won't touch the 32mm SPC adjustment nut to use the extra caster & camber adjustability. They just get glassy eyed as you explain what you have and show them the SPC adjustment instructions sheet. So you won't utilize the full benefit of them unless you do it yourself. I set mine as close as I can before taking it in, which took me about a year of reading different threads to learn how to do. Or find a TacomaWorld buddy in your area who knows how.

 

They just put you to factory spec. Take it to a shop that knows how to align modded tacomas instead of trying to explain what you want to some joe blow that just works on stock vehicles all day. Trust me it makes life easier.

 

If I remember correctly factory caster spec is like 2.0-2.5 degrees. A lot of members like to run 3.5-4 degrees to pull the tire forward and allow larger tires to clear the firewall better.

If you just go to someplace like Firestone they’re going to set it to factory spec. In a lot of cases those places are only allowed to adjust to factory spec. Most basic alignment techs don’t even know how to adjust SPCs and leave it wherever it is set when it comes in the shop.

Your best bet is finding an off-road focused shop that understands how SPCs work. My go to alignment shop specializes in lifted trucks and installs SPCs regularly. They do their best to get it set to whatever numbers you ask for.

You could get much better numbers than that if you find a tech that can work the SPC adjustments.
