Please critique my home front-end alignment method

I doubt you have too much BUT... the higher the caster is, the more they like to wander at slow speeds. Ever rode a long forked bike? As to the number, its like any other specification on the car. If i can know it I want to know it. Not the end of the world for sure.
That's more very good info. I wasn't really considering anything but highway speeds as far as wandering was concerned. Now you're making me want to know the caster numbers. Lol
Just another excuse to buy more tools, I guess.
