Roll Center design theory

[CoryM]

No more than a couple of inches. Less than that on paper or computer b/c more than likely the finished product isn't as dimensionally precise as what you intended.

Good to hear. The setup I have been poking at is 30mm (1.2inch) of movement. Just designing it for the learning experience and I have had a hard time finding out what you usually expect to see for allowable movement.

In which direction, and in what circumstances? Better yet, what does it do in 2" bump and 2 degrees roll? Them's good numbers, but it depends upon the input critera.

CoryM,

Those are good numbers. Give us some pivot locations if you would.....

796spdbu,

Racing of any sort will put you far ahead of the average guy especially if you read a few books along with it. Worked for me anyway :-)

Whatever you do put something on a some kind of track somewhere. You don't want to be one of those lawn chair racers at the car show......

Sorry. I should have mentioned that the theoretical setup is not GM based and is for a (at this point also theoretical) very small car. Also I am pretty green at this stuff so its possible (probable?) that I am missing something important. That was at 3degrees of roll 3" of bump. I will need to buy a real program when I start buying parts for the car and can measure the spindles I want. Hopefully I will know enough by then to figure it out.
Cheers.
