Think of the car like a chair with one short leg. Although only one leg is short the weight is supported by the other two diagonally opposite wheels, and the chair (car) will rock, when going into a corner. Going in one direction the car will feel firm, going in the other direction the car will feel soft. What you need to do is get the "legs" to support as equal an amount of weight as possible. Because of the cars initial weight distribution it will be impossible in most cases to get these weights equal, although top saloon cars will be built from scratch with weight distribution in mind. At best it may be only possible to get each pair of diagonaly opposite wheels to support the same total amount. If this can be acheived then the car will feel much tauter and easier to drive with confidence. This will also depend a lot on chassis stiffnes as to how well the car will respond to adjustments. By shimming the RF wheel you are increasing the load on what is already the highest loaded wheel on a RHD car thus increasing tyre loadings on that wheel. It may be more appropriate to load the RR wheel. Once the car is close to being properly set up, adjustment of one corneer will affect the other three wheels.
