Alignment Problems

Nothing will change the SAI unless you hit a curb or wreck the car. SAI is a built in angle. It is the downward tilt of the spindle when viewed from the front from the steering axis. you'd have to bend the spindle to change SAI. I like to see .5 camber, as much caster as you can get and about .25 degree total toe. Your strut rod bushings should be fine.
