ALIGNMENT SETTINGS - WHAT ARE THE BEST ONES?
The simple answer is that there is no such thing! I know we have probably given more information here than most people wanted, but even this only scratches the surface of the available information and variables that need to be considered when contemplating optimum wheel alignment settings. The most important thing and something we can not stress enough is the fact that alignment settings are NOT an "absolute truth" that can be held up as an undisputed rule. It is a dynamic process with the "correct value" varying from driver to driver, car to car not to mention the driving environment.
DYNAMIC & STATIC WHAT ARE YOU TALKING ABOUT?
Typically used when discussing wheel alignment and geometry. By this, Whiteline are referring to the difference in alignment angles between a stationary and a moving vehicle. That is, the same vehicle will typically have different caster, camber and toe readings when it is moving compared to when the alignment was done in static form in the workshop. In an ideal world, all wheel alignments would be done on a dynamic wheel aligner but these are expensive and quite rare. This concept is very important, as the only suspension angles that really matter are those present while the vehicle is moving (dynamic). What is done to the vehicles alignment while the vehicle is stationary, (static) is a process of trying to predict the levels of change while the vehicle is moving and setting the angles according to these predictions. Whiteline puts a great deal of emphasis on the dynamic geometry so rigorous road testing is essential to ensure that the predictions are valid.

CAMBER WHAT IS IT?
Camber is the inclination of the wheel from the vertical when viewed from the front. When the top of the wheel leans out you have positive camber, lean in equals negative camber.

On a rear-wheel-driven car, acceleration forces on the tyre tend t o push the front tyres back slightly in the wheel well. Static toe-in will result in a zero-toe situation at speed. For a front-wheel-driven vehicle, the front wheels will pull themselves forward in the wheel wells under acceleration. This happens because as the (driven) front wheels claw for traction, they pull themselves forward, dragging the rest of the car along. For this situation, static toe-out will result in a zero-toe condition at speed. Assuming that the rest of the suspension is correctly aligned and maintained, and the tyres properly inflated, toe-in will result in additional understeer for the car. In a corner the inside front tyre will turn at less of an angle than the outside tyre. Additionally, excessive toe-in will result in premature tyre wear through feathering, and increased fuel consumption. Conversely, toe-out will result in additional oversteer for the vehicle. This occurs as the inside front tyre turns at a greater angle than the outside tyre. Thus, in a corner, the inside tyre is trying to turn even more than the heavily-loaded outside tyre. Excessive toe-out will also result in premature tyre wear due to feathering, and increased fuel consumption. *"Anti" Geometry* "Anti" features in suspension systems are a characteristic that can be used to influence the stiffness of the front or rear suspension under traction forces(under braking or accelerating). The individual terms are relatively straightforward and self-explanatory with the educing or totally restricting the characteristic (lifting or diving). In the front suspension there may be levels of anti-dive during braking and anti-lift during accelerating (assuming traction to the front wheels is present), similarly in the rear there could be anti lift during braking and anti-squat during acceleration. It should also be noted that these characteristic can also be reversed into a haracteristic (as in pro-lift at the front under braking). Anti features can only be implemented under the influence of the braking or accelerating forces at the wheels, for example a rear wheel drive vehicle cannot have an anti-lift characteristic in the front (as there is no drive to the front wheels). With the ALK fitted to the Subaru WRX, a softer suspension will be present during braking and accelerating. This will help traction, as the wheel will be able to track the ground more precisely. Also in terms of balance the front end will have a proportionally lower roll resistance during traction or braking, aiding in reducing the power understeer effect that is present in these cars.
