Questions regarding alignment numbers.

Got an alignment yesterday after replacing LCAs and hardware, upper ball joints and a wheel bearing.
I don't know what SAI and included angle are, but as you can see, they're red on the drivers side.
What do these numbers represent?

 

Steering axis inclination is built into your suspension. Here is a video that is pretty good at explaining it. Included angle adds or subtracts the camber of that tire from SAI. I wouldn't read too much into those #s unless you are having driveability issues with tracking or weird handling. When the numbers are way off from factory they can be used (by a good tech) as ways to look for bent or worn steering and suspension components.

I'd have to say worn of anything. And at this point, the only thing left is UCA themselves as everything else is new or in the case of the tie rods maybe a year old. Thankfully they're still tight.

 

I wouldn't worry with them then.
