1. A suspension for a vehicle, comprising:
a knuckle adapted to support a wheel hub;
a lower control arm interconnecting a lower portion of the knuckle, at a lower connection point, to a structural member of the vehicle, wherein the lower control arm is pivotally connected to the structural member of the vehicle and pivotally connected to the lower portion of the knuckle;
an upper control arm interconnecting an upper portion of the knuckle to the structural member of the vehicle and including an inner segment and an outer segment, wherein:
the inner segment of the upper control arm is pivotally connected to the structural member of the vehicle;
the outer segment of the upper control arm is connected to the upper portion of the knuckle at an upper connection point; and
the inner segment and the outer segment are pivotally connected to one another; and
a camber gain link interconnecting the upper control arm and the lower control arm, the camber gain link connected to the upper control arm at the pivotal connection of the inner segment and the outer segment;
a pivotal position of the inner segment relative to the outer segment defining a lateral distance between the pivotal connection of the inner segment to the structural member of the vehicle and the upper connection point and an effective length of the upper control arm;
the knuckle pivotally moveable about the lower connection point, such that the effective length of the upper control arm defines a camber angle of the knuckle; and
the camber gain link adapted to secure the pivotal connection of the inner segment and the outer segment and prevent pivotal movement of the inner segment and the outer segment relative to one another, thereby establishing a pivotal position of the inner segment relative to the outer segment, the effective length of the upper control arm and the camber angle of the knuckle, and including a first distal end that is connected to the upper control arm at the pivotal connection of the inner segment and the outer segment, and a second distal end that is connected to the lower control arm;
wherein, changing a position of the pivotal connection of the inner segment and the outer segment relative to the lower control arm, changes the effective length of the upper control arm and the camber angle of the knuckle.
