Sounds like toe, and/ or 'tram-lining' just due to the tires themselves (the grippier the tire, the more pronounced). Assuming the bushing are all okay, check the toe.

Toe-in is 'safe', and how auto manufacturers set up the cars. Toe-out has much quicker steering response (initial turn-in), which can make the car 'darty'. Good for track and auto-x, but the amount of toe-out should actually be pretty small. For pure street driving, a little toe in is probably best, or maybe zero toe.
