Which term describes the angular relationship between the steering axis and the vertical when viewed from the front?

Explanation:
From the front, the angle between the steering axis and a vertical line is what we call Steering Axis Inclination. The steering axis is the imaginary line through the upper and lower pivots of the steering knuckle, and SAI measures how that axis tilts away from vertical in the front view. This tilt helps with straight-line stability and you’ll also see related effects on how the wheel camber changes as you steer. Toe, camber, and caster describe other wheel alignment aspects, so the term that fits this description is Steering Axis Inclination.
