i'm dropped about 3", and when I had my stock wheels on, I didn't feel a need for an alignment cuz my tires were fine and everything. But when I got my new wheels, they were so wide that the toe in the front would jerk my steering wheel back and forth, so after that I had to or else I'd crash haha. So yeah, I mean, I would get an alignment a week or two after you drop it just to be safe.
