Vehicle Alignment Question
I was just curious, I plan to lower the front of my Ford Ranger 1-inch by replacing the front springs with a shorter springs. But lowering the truck will change the suspension geometry.

The I-Beam is 34-inches long. It moves up and down in an arc, if I lower the truck 1-inch then the tire lean (camber) changes. But How Much?

This is what I've figured out so far, am I on the right track? If so what is the angle measure between the two lines?

Re: Vehicle Alignment Question
the central angle equals the angle in question.

dropping vertically 1" is very close to an arc length of 1" ...

$\theta = \frac{s}{r} = \frac{1}{34} \cdot \frac{180}{\pi} \approx 1.7^\circ$

I should have realized that. Thank you.
