4 link suspension geometry

[itmejeremy]

Hi everyone! I have been lurking around this forum for a little while as a guest and finally decided to sign up. Great forum!!!! I am trying to do some homework before i start my project and i was wanting to learn more about suspension geometry. For example: I know with a solid axle rear end what ever is used to hold the rear end laterly (panhard bar,triangle upper links, watts link and so on) is where the roll center is located. My question is don't you want the roll center as high as you can go so it is closer the the Center of Gravity? I read somewhere that if you have too high of a roll center then it won't work right either. So with a four link suspension how much is too much on the roll center height? Also how critical is it. Would you notice it if it was a little lower roll center? I think that make sence. Thanks in advance for any clarification or tips.
