For a torque arm suspension, the instant center is located on a vertical line that passes through the chassis mount of the torque arm. When a line that passes through the lower control arm is extended to the vertical line determined by the torque arm, the point at which these two lines intersect is the instant center. Extending a new line from the contact patch of the rear tires through the instant center all the way up to the front of the vehicle determines the value we need to determine the antisquat. This new line determines a point on a vertical line passing through the center of the front tires. The height of this point divided by the center of gravity (times 100 for a percent) of the vehicle is the antisquat value.
