The suspension of a vehicle is measured in three different ways, on different axes. Just remember that camber is all about finding the right balance for your car and its purpose. You’ll need to consider your car’s intended mission when customizing its camber settings. Same goes for off-road trucks and sporty coupes. For example, a performance vehicle in a professional racing circuit, doing laps around the Nurburgring, or at a local track, may have different camber requirements than a family sedan. Your car’s mission – or purpose – also comes into play. So, settling on the right camber angle can extend the life of your tires and save you some money down the road. For instance, excessive negative camber may cause the inner part of the tire to wear out more quickly, while excessive positive camber can cause uneven wear on the outer part. When it comes to quality of life, proper camber settings can directly impact your tires’ lifespan. A well-set camber angle can improve your car’s stability and cornering ability, ultimately making your driving experience more enjoyable. This means that most vehicles are designed to have some camber, since having this static camber can lead to zero camber on some of the tires during turns.Ĭamber plays a critical role in your car’s handling. Body roll changes the size of the contact patch as the car and tire lean, which reduces lateral grip the tire is able to provide. Tires at zero camber, or neutral, have the largest contact patch and the most grip (and stability) in a straight line. The amount that this camber changes while turning is called camber gain, and depends on the type of suspension. Camber changes the contact patch, or area of tire contacting the ground, which affects grip.Ĭamber angle is measured while the vehicle is not moving (static camber), as the camber naturally changes while the vehicle is turning, or cornering, due to body roll. The ideal camber balances tire traction and tire wear, and thus varies for each vehicle depending on how it’s driven, road conditions, suspension type, amount of grip in the tires, and type of vehicle. The tops of the wheels can lean either towards or away from the center of the car when viewed from behind. As the steering axis is inclined, the wheel naturally wants to return to its original straight position which is the reason why your steering will self-centre after a steering input.Camber refers to the angle of the wheel and tire relative to a perfectly flat road. Due to the angle between the two control arms connected by the kingpin, the wheel naturally wants to follow the path of least resistance once it has turned. To coincide with this inclination, the wheel itself is set at a slightly positive camber to allow the tyre to rotate through steering inputs more easily. This scrubbing vastly increases tyre wear and input effort, and therefore the steering axis is inclined to minimise the size of the scrub radius. The scrub radius is the path along which the tyre has to travel along the ground to complete its steering arc. The axis of the steering system, if left vertical and in plane with the tyre, results in a large scrub radius for the tyre to rotate through. This inclination is between the ends of the steering control arms, with the axis being governed by the kingpin between the two. Some vehicles use positive camber - with the top of the wheel angling outwards - due to steering axis inclination.
