if you have standard wheels and all standard hight and everything standard then yes use the factory specs.
But if you have modified anything or have big wheels or offset changes then any reputable/knowlegeable alignment guy can make it work.
For example I run 20's and my wheel aligner has taken some of the caster and camber out to make it handle better.
It sure worked! find a good aligner is the key.
Also if ANY component of your suspension is shot like bushes or ball joints. then its going to be a complete failure. again if anything needs to be replaced a good aligner guy will tell you.
