An illustration of a wheel with negative camber. Camber is a measurement from the centerline of the wheel/tire relative to the road's surface. Negative camber is when the top of the wheel/tire angles inward toward the center of the vehicle. When done sparingly, negative camber greatly improves the handling characteristics of a vehicle.
The 1960 Milliken MX1 Camber Car has a large negative camber. Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear.
MacPherson strut equipped vehicles usually have a negative scrub radius. Even though scrub radius in itself is not directly adjustable, it will be changed if the upper steering axis point or spindle angle is changed when adjusting camber. This is the case on a MacPherson strut which has the camber adjustment at the steering knuckle.
Bump steer can become a problem when cars are modified by lowering or lifting, when a spring has become worn or broken causing a lower ride height, or if the vehicle is heavily loaded. When a car is lowered or lifted, the wheels' toe setting will change. When a car is lowered or lifted, it will have to be re-aligned to avoid excessive tire wear.
2. Zero Camber The vehicle is said to have zero Camber when the wheels stand perfectly straight on the ground. 3. Negative Camber Negative Camber is encountered when the top of the wheels lean inwards. Providing Negative Camber improves the cornering performance. When the vehicle turns on a corner, it performs a circular motion.
The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement is titled an "SLA" or "short, long arms" suspension. When the vehicle is in a turn, body roll results in positive camber gain on the lightly loaded inside wheel, while the heavily loaded outer wheel gains negative camber.
I also felt like adding a section dedicated to camber wear to explain how positive and negative camber effects tire wear differently. There wasn't quite enough information on the effects of camber in a straight line, so I added a couple more effects on camber in a straight line. 95miata 02:34, 22 September 2022 (UTC)
Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
