1. ## 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?

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.
