Bump Steer is ruining your handling... (Easy Fix)

Why does your car steer itself when you hit a bump? It could be bump steer—one of the most misunderstood suspension geometry issues that affects everything from street cars to dedicated track builds. In this episode, the KONIG Wheels team explains what bump steer is, what causes it, how suspension geometry affects steering, and how to fix it. Whether you've installed coilovers, lowering springs, adjustable control arms, extended ball joints, or modified your steering rack, understanding bump steer is essential to achieving predictable handling and proper steering response. We'll break down how tie rod angle, control arm geometry, suspension travel, toe change, ride height, steering rack position, and wheel alignment all work together—and why lowering your car without correcting suspension geometry can negatively impact handling. If you're building a Honda Civic, Subaru WRX STI, Mitsubishi Lancer Evolution, Nissan 350Z, Mazda MX-5 Miata, Toyota GR86, Ford Mustang, BMW M3, or any performance street or track car, this is suspension knowledge every enthusiast should understand before modifying their vehicle. In this video, we discuss: -What bump steer actually is -How bump steer affects steering and handling -Suspension geometry explained simply -Why lowered cars develop bump steer -The relationship between tie rods and control arms -How toe changes during suspension travel -How to diagnose bump steer on your own car -Bump steer correction kits explained Whether you're building a daily driver, autocross car, time attack build, drift car, road race car, or weekend canyon carver, understanding suspension geometry is one of the best investments you can make before purchasing your next set of wheels or suspension components.
