Definition

Bump steer-- is the introduction of steering input caused by a bump in the road surface. When a wheel travels up and down over a bump, it actually swings in an arc. If the steering tie-rod does not swing in the same arc as the suspension, the wheel will have an increase or decrease in toe and will result in a slight steering effect. Virtually all suspension geometries on street cars have some degree of bump steer, through it will be very slight. However, modifying a car's suspension by using lowering springs can increase the amount of bump steer. Bump steer causes tire scrub, and loss of traction if experienced during cornering. If you're altering you car's suspension, measures should be taken to minimize or eliminate bump steer.
