A High Performance Steering System for amplifying the turning motion of an axle as the turning motion is applied to wheels or tracks at the outer ends of the axle. The present invention generally includes a support member such as an axle which is secured underneath the frame of a vehicle such as a garden tractor or automobile. The support member includes a fixed post and an outer post for each wheel that is steered. Wheels or tracks are connected to the outer posts, such as by mounts. Rotation of the support member imparts forces through sprockets, gears, pulleys, tie rod linkages, or the like to amplify the turning motion of the support member as it is applied to the outer post. The amount of such amplification of turning motion between the support member and outer posts may be varied with differing size ratios of the sprockets, gears, or pulleys.
