Here's an excerpt from the new Hudy Setup Book which should be available for download from the website soon:
Caster angle affects on- and off-power steering, as it tilts the chassis more or less depending on how much caster is set. Generally, a lower caster angle (more upright) is better on slippery, inconsistent, and rough surfaces, and a higher caster angle (more inclined) is better on smooth, high-traction surfaces.
More caster angle (more inclined) has the following effects:
• Increases straight-line stability.
• Decreases steering at corner entry.
• Increases steering at mid-corner and corner exit.
Note that depending on the track surface and tire hardness, these effects may be different in that you may always have more steering with more caster. This is especially true for high-traction tracks and/or soft tires.
