A = don't worry about A, don't touch A B = Adjusting Bolt/nut C = Rear housing Adjuster arm / Anchor Arm D = Torsion Bar If the rear is sprung too lightly for the load it carries, then excess load transfer will occur at the front and the left front tire will have much less loading on it at mid-turn. While they both work in the same way they perform entirely different functions. The suspension has a straight axle for both the front and rear, the driver sits in the center of the car, the rear axle is supported inside birdcages, the rear tires are much larger and wider than the fronts, especially the right rear, and the cars are sprung with either a coilover spring/shock combination, torsion bars, or a combination of both.
