A useful design tool is antidive and prodive. Antidive keeps the front suspension from moving too quickly and too far. Prodive causes the front suspension to move more quickly. These two only work while we are braking, and that is exactly when we need them to work. Antidive is accomplished by angling the control arms from a side view so that as the spindle tries to rotate under heavy braking, the motion of the ball joints is in the reverse direction and resists dive. Prodive works in an opposite manner.
