Discussion and questions related to the course Motorsport Wheel Alignment Fundamentals
What's the principle of that we steer 20 degree to measure castor?
Caster (American spelling) turns into Camber when you turn the wheel. By turning it a known amount(20 degrees), and measuring the camber, we can calculate the castor (British spelling)
Can I just on this thread a bit ( sorry )
Can caster be worked out with just a camber gauge? I know about the 20 degrees turning, but in the practical demonstration a caster gauge is always used which works it out for you.
Is there an actual calculation that can be done in order to work out the caster?
I think this equation will work:
Caster (deg) = (180 / 3.1415) * [(camber1 - camber2) / (turnangle1 - turnangle2)].
Here is another suggestion if you can zero your camber gauge:
Hi David, thanks for the reply, I have longacre camber gauge so I can zero it to carry out what is described on that website.
Where did you find that equation, looks complex!
I'm pretty sure I googled "calculate caster angle"....
