Guys,
Caster at an extreme angle can and will raise the rear inside tire in a turn. This isn't a good thing. This means you need a stiffer spring or thicker oil as was said by mittimj. Caster does add camber when you turn the wheels. If you run a lot of caster you need to dial all the camber out when the wheels are straight and make sure that all the tires are making contact with the track in the turn. It isn't good to unload the tires in a turn. You want the most traction you can get to pull out of the turn the quickest. As for go-carts, I race them to. The reason the rear inside tire lifts from the ground is because there is no suspension. The reason that happens is because the chassis from your high centre of gravity is flexing. It isn't supossed to do that but it does because of the speed carried through the turn and it is flexing. Hope this helps you out. As said, if you knew what you were already asking then you shouldn't have posted and caused this frustration between members.
