Hi,
I have a Lynx B and it comes with some positive caster. This is built in, it's set with the way the H beam is bolted onto the frame.
When looking at modern frames, like the Lazer for example, it seems there is no caster, the H beam is perpendicular to the frame.
When I was running go-karts caster was a key setting, it allowed the gokart to switch to 3 wheels in corners, making it easier for the rear axle to go through turns (since there's no differential) with minimum drag. I'm guessing this is not an issue on a FV. I've read the only (?) effect of caster in a car with a differential is to make the car more responsive to steering input (the more positive caster, the more the car will be responsive).
Is this the only effect of caster? Why do modern FV cars seem to have no caster? What's a typical caster setting? Do people adjust caster, with shims for example between the front axle and the frame?
Thanks,
Jean
