Total noob question, but how do you know when you need an alignment? Pretty much only if you lower or your car isn't driving straight, right? Cause after my wreck in November I got an alignment and the car drives straight as an arrow. And I'm at the stock height, if not higher . But when I get my new tires put on, I wanna make sure I shouldn't just get an alignment while I'm there too. They're like $60 though, so I don't wanna get one unless I need it. Thanx for the help.
