Couple of questions, also please redirect me if I'm off, I'm struggling to get a better grasp of suspension kinematics.
1. I was wondering, is there an optimum amount of camber gain desired? The way I understand it is a little bit of gain is good in order to rotate the outside wheel to increase tire contact patch. But at what point is it affecting the roll center too much?
2. Where do you place a roll center? If it's above ground, you can get jacking forces, but are they necessarily bad? since the car is being pushed up, that means the tires are being pushed down. If it's below ground the car will tend to squat, which I can see would lower the center of gravity... is this the only reason the roll center is sometimes placed under ground due to the CG?
3. And finally, does anyone know of a good animation of roll center migration?
