Bump steer is the change in a car’s toe angle as the suspension compresses. As you push your car down, you'll notice that the toe-in changes - this effect is called bump steer, and the amount of bump steer your car has can be adjusted by changing the vertical angle of the steering links, either at the inside (rack) or at the outside (steering arm.)
Be aware that if you change your car's camber link locations, toe, or kick-up, you may need to re-adjust your bump steer to keep the handling characteristics consistent.
Less bump steer
- Increases toe-in (decreases toe-out) when suspension is compressed. See our toe article for the impacts of the toe angle.
More bump steer
- Decreases toe-in (increases toe-out) when suspension is compressed
Active toe is similar to bump steer, but in the rear of the car.
