It is typical for alignment shops to set the passenger side caster to a slightly greater amount than the river side setting. For street-driven cars, a difference of 1/4° to 1/2° will help counter the effect of road crown, and prevent the car from pulling towards the right on most roads.
Unlike camber, there are many variables that affect the caster. For example, if the car has any rake, the measured amount of caster will be less than if the car was level. Changes in ride height will affect the measured amount of caster. Different technicians using different alignment equipment will measure caster at varying amounts. Unlike camber, the number of degrees that caster is set to does not have to be exact. As long as caster is in the desired range, and the difference from one side to the other is not greater than 1/2°, it is acceptable.
On the other hand, camber should be set very carefully.
- Street-driven cars: 1° negative, /-1/4°. Keep a close watch on tire wear patterns, and adjust camber to reduce poor wear, if necessary.
- Race cars: Depends greatly upon the track, driver, etc. Usually set around 2° negative as a starting point. Adjustments should be made after checking tire temperatures and wear patterns.
- Street-driven cars should be set at toe-in for straight-line stability. They can be set to the factory specification of 0.5° toe-in.
- Competition cars are typically set up with some amount of toe-out, for quicker turn-in response and increased front grip. A typical starting point would be 0.5° toe-out.
Remember that any time any change is made to the camber setting, the toe setting will be affected, and must be readjusted. It is a good idea to always keep a record of the alignment settings. Inspect the tires frequently for uneven tread wear patterns. If uneven tire wear becomes evident, have the alignment adjusted. With a record of the previous alignment it will be easier to diagnose the problem and make alignment adjustments to improve tire wear.
