Camber gain is added angle to the ground. Body roll is subtracted angle to the ground. For example, if your car handles pretty flat, you might compress 1" on the outside (in a hard turn) and lift 1" on the inside. Seems reasonable... and inch isn't a whole lot. Well 2" of difference total and a 66" width, throw some Sine in there and it's about 2* of body roll. That's 2* of camber angle you've lost. So if you had 2* static camber and no camber gain, the tire would be completely vertical. Camber gain is adding a few degrees to keep a good angle to the ground during a turn. Want less? Decrease the camber gain or run less static camber. You don't need any camber to go straight. You need it in turns. Wouldn't you want a model where camber increases as compression/effort increases? BTW, camber also decreases in lift on inside of the car. That's the other side of camber gain under compression... camber subtraction under lift.
Also BTW, slammed cars have very little to no camber gain in the front due to geometry. Tendancy to understeer, anyone?
Thanks for the reply. I do understand what you are saying, but I think I just have a different opinion still. For instance, camber curves are only consistant to a certain point, and it seems the arm length directly effects the amount of time that they stay that consistant. So like I said, the shorter arm will bring the compressed wheel's camber in further than what seems desireable, and before you know it, you have two totally unrelated wheel/suspension angles in that hard corner. If I have a longer arm, I will be able to keep a more specific camber angle throughout the entire turn (it will take longer for the camber to change under compression/lift)...
p.s. - I know what i'm thinking, but i had a really hard time putting it into words, or at least typing them. sorry if I'm still unclear, haha.
