NEGATIVE CASTER 1

[bkndesign]

I´ve been working on a new front suspension for our 1250 kg, rear wheel drive, 350 hp, no power steering race car, and found out that the weight transfer on cornering is great when i use negative caster. But this produces a great deal of instability due to the caster trail that results, and also i found out that i will need more negative camber. Is something i can do before starting to design a new upright?, and then what should i take into account to use negative caster?

What problem are you trying to solve by throwing away front grip, that can't be addressed otherwise?

As your experience suggests, negative caster becomes positive camber as you add steering lock. Most times I think a more positive caster setting is desirable so that static camber doesn't have to be as extreme (consider how the front tires become inclined during braking).
