Caster adjustment degree readings

[jimsmonte80]

When doing a caster reading, the wheel is turned in 20 degrees and the camber gauge is zeroed. Then the wheel is turned out 20 degrees (total of 40 degrees) and the camber reading is recorded. The recorded reading is then multiplied by 1.5 to for the caster reading.

However, if the wheel angle is turned 15 degrees in, then 15 degrees out (total of 30 degrees), you multiply that reading by 2 to find your caster reading.

So what if you turned the wheels 25 or even 30 degrees. How does that affect what number you multiply your caster reading?

why would you want to ? 20 in and 20 out is the angles you do all your driving and i never multiplied by 1.5 the reading is the caster

When doing caster readings, you are measuring the camber angle at 20 degrees in, then twenty degrees out. This is a total of 40 degrees from right to left on the driver side tire. So turn the wheel in 20 degrees, zero your camber angle gauge. Turn your wheel 20 degrees out, measure your camber angle reading. Take this measured camber reading and multiply by 1.5 to find your caster angle. Now if you turn your wheels 30 degrees either way, you will get a more accurate caster reading. But what number are you multiplying by? Because you multiply by 2, when your doing a 15 degrees. So what number do you use for 30 degrees?
