Bump steer is something I would like to eliminate with my car.

Thanks to your input I now have a basic understanding of what I need to acheve (See previous thread under chassis construction banner by me)

Does anyone have any formulas for the workings of geometry. If so then please could you post it here and I will write a computer program that works it all out for you.

Vince,

There's a free program for suspension geometry, including bumpsteer, called Wishbone available at RaceTech magazine in the downloads area.

There's been much discussion about geometry and bump steer on the Yahoo Locost Theory list, so you may want to check that out.

Best of luck,

Pete B.

there is a free program for DOS in TOL files area called 'suspension helper' - can also be used to work out bump steer.
