off road Coil over selection

[jayfeather]

I am the project manager of a Baja SAE Team. On one of our cars we have decided that we would need heavier springs to accomodate weight added to our car. Approximately 120 pounds added at the CG. We would like to select springs that will give us the same handling dynamics as the previous setup. We run a spool and rely heavily on a lighter roll rate in the front allowing the inside rear to lose contact during body roll and the outside rear to create a large yaw moment. how should I go about the selection? weight distribution, motion ratios and ride height? natural frequency?

Thanks,
Joe

What university do you go to? I go to clemson, but I have nothing to do with our baja SAE... I own my own baja toy!

Anyway, the best way to tune a desert style suspension is with frequency. What are your corner weights? What shocks? suspension travel?

If you like the way it handles now stick with the same freq. ratio (front to rear. Use a tighter dampener to compensate for the weight.
