The past hours Ive been searching for info about how to meassure the caster on a car/on my s13.
I know how to meassure camber, and adjust toe...
The only info i found was here: Sheldon's DIY Miata Alignment Page
And this formula: Caster (deg) = (180 / 3.1415) * [(camber1 - camber2) / (turnangle1 - turnangle2)]
I dont really get it, how its done.. can someone help me out?
