1956 F100 (Project Fat Max) Build Thread

[Dr G]

Here is another screen capture from the Suspension Analyzer software. It shows how my current design behaves under 3° roll and 0.7" of rack movement (steering input). See the numbers I've outlined in Green:





This is where the effects of caster come into play. In one way it is possible to think of caster as inducing "dynamic camber". With 11° of caster, and with the wheels turned to the left some 10°, the outside front tire is still at -2° camber, even though the chassis has rolled 3° to the outside. The plus side of this effect is that you can run less static negative camber. This would help with braking and tire wear. But too much caster has negative effects also. Heavy steering due to increased trail is one such effect. Ron Sutton mentions some of the other side effects in his excellent suspension summaries.
