Re: bump steer

Julian
That really is simple but must be pretty effective.

Can on of the Gurus please explain at what ride height the chassis should be to set the bump steer? Presumably it is set at a nominal (say)4.5 inches. But correct me now if I am wrong the bump multiplies the further from neutral you go, so do you try and set it with less movement under braking (Say) 2.5 inches to end of travel or when under power (Say) 5.5 inches.

Reason I ask is if you are doing 120mph (or more) and the nose is up higher than at rest and you get movement the resulting car "wander" could be uncontrolable compared to under hard braking the "wander" would be less (Lower speed times change of angle).

Yes I accept you are trying to minimise the movement but at what end of the travel is the lowest movement required?

Thanks
Ian
