I'm useing firestone and just paid for there lifetime Alignment and dont like the way they just did it , so I have to go back ,but would like to have the right numbers in hand to see if there specs are off or different.

This is going to come out terrible, maybe even unreadable, but it's in a table and they just don't cut/paste well into a plain text post. Hope you can make sense of this...

Model

Caster degrees

Camber degrees
