Caster Angle Explainer | Steering Stability & Effort Effects
Understand wheel caster angle (positive, negative, zero) and its influence on steering stability, self-centering, effort, and cornering dynamics. Interactive explainer.
Caster is a key wheel alignment angle, referring to the tilt of the steering axis when viewed from the side of the vehicle. * **Positive Caster:** The top of the steering axis tilts rearward. This is the most common setup in modern vehicles. * **Negative Caster:** The top of the steering axis tilts forward. Rare in most cars. * **Zero Caster:** The steering axis is perfectly vertical. Proper caster angle significantly impacts straight-line stability, how the steering wheel returns to center after a turn, steering effort, and even cornering dynamics by influencing camber change during steering. This explainer helps you understand these effects.
- Enter the desired Caster Angle in degrees. Most passenger cars use positive caster, typically between +1° and +7°.
- Adjust the value using the input field or the `+` / `-` buttons for live updates.
- The results will explain the type of caster (Positive, Negative, or Zero) and describe its general potential effects on vehicle handling and steering effort.
- An illustrative placeholder image will also be shown to help visualize the angle.
