what can be caused from excessive negative caster. Camber refers to the angle of the wheel and tire relative to a perfectly flat road. The simplest way this can be fixed is by using a healthy driver and rider. Negative Camber Effects. Excessive negative camber can cause the wheels to tramline, or follow cracks in the road. Take readings from the middle of the tire, along with the inner and outer edge. The benefit of this angle is for making turns around corners because the wheels and tires are positioned better for this purpose. Hi all: I've got an excessive front passenger side negative camber wheel situation that I'm hoping someone can help me with. When your front wheels have a negative camber, they are inclining inward. Tires at zero camber, or neutral, have the largest contact patch and the most grip (and stability) in a straight line. how much they lean in and or out). 2. This means the coil spring over the shock, or coil over, would be going toward the rear while you’re driving. This offsets the tendency of the outside front tire to roll onto its outer edge (positive camber) because of body roll during the turn, which would reduce grip by decreasing the contact patch size. Next step: go racing. Camber plates are easily adjustable which makes them flexible for different driving conditions (i.e. This is measured by a pyrometer, also known as a non-contact infrared thermometer. Prospect62 Full Access Member. As your car leans left, both tires lean left as well. It can also be measured (albeit less accurately) with a bubble level and a camber gauge. Negative camber is implemented so that when the car is cornering and the wheel is rolling over and gaining positive camber, the negative camber should correct whatever effect leaning and lateral load have on the wheel and tire; resulting in the greatest possible contact patch. Camber is a tire wearing angle. Negative camber improves handling by keeping the tire perpendicular to the road as the car rolls; ensuring that the tire's contact patch is evenly loaded. The rear wheel camber is not adjustable from the factory which is why having an alignment performed usually doesn’t help. Camber is considered negative, when the tops of the tires lean in-wards. The body of the car has inertia and wants to keep going straight. Calculates optimal camber from config files - per car, per tire compound. Hence excessive negative camber normally first manifests in uneven tire wear, with inside edges wearing much quicker than the rest of the tire. Hey guys. Camber 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 downside of running more static camber, besides tire wear, is that it reduces your tire’s contact patch in the straights, making it more difficult to put down power. Excessive positive camber will be exhibited by excessive wear on the outer edge of the tread due to the excessive outward lean of the upper edge of the tire. A car with a McPherson setup, (or worse, a live-rear axle), will not gain camber. See Also:  How Much Does a Wheel Alignment Cost? The amount that this camber changes while turning is called camber gain, and depends on the type of suspension. Too much extended camber can affect those hard stops that may be necessary. This occurs when negative camber wheels naturally propel the vehicle towards its midline. Performance cars need increased stability when turning, as turns are done at much higher speeds than normal. Usually somewhere between 1-2 degrees is a good place to start. sensitive steering at high speeds, causing wander. Messages: 436 Likes Received: 0 Joined: Jun 11, 2007 Location: New Hartford, NY. The predominate alignment issue with this particular tire was excessive negative camber and not toe. Camber is best measured by a professional with specialized equipment, such as an alignment rack. 79. 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. To "measure camber, use a level across the wheel, top to bottom (plumb).
