Defective springs negatively affect vehicle handling and road safety: They extend the stopping distance because they can no longer correctly absorb the forces which occur upon deceleration. In addition to that, tires lose road contact more easily and wear more quickly. In fast or tight corners, the car has a greater tendency to move sideways and will break away earlier. If the vehicle accelerates or brakes, the body is subject to substantial movement. Furthermore, the ground clearance is reduced, which in turn increases the tendency to "bottom out". Not least, damaged springs reduce the service life of dampers.
