Discussion on caster

Yes, this is correct. More caster gives more camber as the wheel is turned. However, the steering axis inclination works against this.

Correct me if I'm wrong, but if your steering axis inclination was equal to your caster, then you would get no change in camber as you turn the wheel. More steering axis inclination than caster will make the outside tire gain positive camber with increased steering angle. More caster than steering axis inclination will make the outside wheel gain negative camber with increased steering angle.

I wish we had dual a-arms all around. It makes all this stuff so much easier. Mac struts make it hard to isolate one characteristic. Even if you have all the caster/sai/camber where you want it, as soon as you have any body roll, the camber changes as well.

There is also the Whiteline Caster bushings. You don't have to sacrifice the adjustability of camber for caster. You can have both. I assume the bushings can only get you so much though. How much do they allow you to adjust?
