I have my Crossfire SRT6 in for a alignment at a tire shop and was told the front is off about a degree, whatever that means.

He said that might be how it came factory because of the type of car it is, and mentioned something about casters....?
Sorry I don't have much detail but I just spoke briefly on the phone.

What is a caster and does that apply to the SRT6?

Does this sound right?
