Care to explain that one? |
Sure - springs & bars control load transfer of the sprung mass, which is one of the components of overall load transfer due to lateral acceleration in a corner. As you stiffen the springs and/or bars at a pair of wheels (front or rear) more load (weight) transfers from the inside wheel to the outside wheel. Due to the inherent characteristics of pneumatic tires (lateral force produced vs. vertical normal force), a pair of tires will produce their maximum possible total lateral force when they are equally loaded. Consequently, the more load transfers from inside to outside in a corner, the less total lateral force that pair of tires will be able to produce - i.e. you have decreased the available grip at that end of the car.
