Bump steer in a race car should be minimized because it could fight everything that the driver is trying to accomplish with the steering wheel.  In general, the rougher the track's surface, the more important it is to minimize bump steer.  This can be accomplished with our bump steer gauge. 

Comes complete with excellent instructions and aluminum storage case.
