What's the best way to adjust the toe and camber. I have been eye-balling it but im sure there is a better way that's not SO technical or doesn't require buying a special piece of equipment.
You can make angles with a protractor and a piece of cardboard. I use a ruler for toe. That's about as cheap as it can get.
Well, you can buy the guages for both toe and camber from RPM for around $10 each. Other than that, Billy's suggestions are spot on. A long ruler can help with eyeballing it, and a square if you have one.
