It's typical for the SAI to be out on both sides. Even brand-new cars with <1000 miles are like that in many cases.
It is not a tire wear issue, and on a super high performance car, you may notice a difference in very fast corners that it handles differently left to right.
Don't worry about it.
If you think yours may be messed up...ThunderbirdJunkie is aligning his KJ tomorrow (to compensate for suspension sag now that the OMEs are broken in), and he can scan the sheet for you
It is really FUBAR
Toe is the only one that you really have to worry about...as long as camber and caster are not more than about 3/4 of a degree off side to side, a KJ with big tires should not pull.
