Another negative side effect of lowering your Evolution can be the induction of bump-steer. Bump-steer is the concept of bumps or imperfections in the road causing a car to steer off-track on its own without any driver input. This is described by many Evo drivers as needing constant direction correction when steering over a bump. This annoying and sometimes even dangerous effect is the result of poor suspension geometry when a vehicle is lowered below factory specs.
Many Evo owners simply learn to live with this issue, but that is no longer necessary. Whiteline has developed their Evo specific tie rod replacement, known as the bump-steer correction kit. The bump-steer correction kit extends the factory front end tie-rods to keep the axles at nearly the same distance from the frame at the steering box, eliminating axle tilt and subsequently curing bump-steer. This kit is specifically designed to work in conjunction with the Whiteline roll-center kit and is highly recommended for any and all lowered Evolutions especially those that see daily or any street driving.
