Default Best Alignment Specs??

Hey guys getting an alignment this week, I’ve seen many threads about ppl doing “better” than Lexus’s recommended specs but a lot of the information is conflicting. My cars a 2015 IS350 FSport AWD, could someone recommend the “best” alignment specs?

Lexus specs are the best:

Toe ..
Front RWD: 0.0
Front AWD: 0.05 (toe in)
Rear AWD/RWD: 0.18 (toe in)

What about camber and stuff? in this thread is that exactly what you told them to do to yours?

I did the Lexus specs. The machine graph will give you different results if the just try to go to the center point.

I have to check camber, but I wouldn't change it much. Only front is adjustable and only on AWD

on the other thread you said your front camber is 1.2 would you have it set there if you did it again?

1.2 in front is good.

There's no "best" spec. Alignments are a spectrum. Just depends where on the spectrum you want to land. Tire life/comfort or performance/agility.

This is why you'll see all kinds of answers. Also a lot of "car guys" misunderstand alignments and spew all sorts of misinformation.

So the first question you have to ask yourself is "what do I want"

You also have to ask yourself what adjustments are possible on your particular make/model of car
