[Rooster's 67]

here is a pic of a caster/camber gauge, not all that expensive by any means, just requires turntables to go with it, also makes it hard to align with thrust angle, but accurate measuring can get that close. you wont have any pulling or excessive road drift with less than 1.5 deg. cross caster.
