Bumpsteer Definition: Bumpsteer is a change in toe angle caused by the suspension moving up or down. Bumpsteer is built into the geometry of the suspension and steering system, and occurs independent from any steering wheel input. The effect of bumpsteer is for the wheel to toe-in or toe-out when the suspension moves up or down.
This toe change or ?steering? occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Excessive bump steer that occurs from lowering or altering suspension geometry is undesirable because the suspension is giving you unwanted steering inputs from the excessive toe changes.
