It has become common practice to replace the stock rubber control arm bushings with solid or two piece polyurethane bushings to resolve the shortcomings of the soft rubber bushings. Hard polyurethane bushings eliminate wheel hop, reduce axle deflection, and improve rear straight line grip. However, the downside of common aftermarket bushings such as delrin, steel, stiffer rubber, solid or two piece polyurethane bushings is they prevent the necessary movement of the control arms during body roll, which in turn produces significant binding in the suspension when the vehicle is cornering. The polyurethane bushings also place unnecessary high stresses on the torque boxes, which are the attachment points for the control arms to the chassis. Standard aftermarket control arms do not allow for rotation of the control arm during cornering because of the stiffness of the bushings.
The INEXPENSIVE solution to suspension bind in 04 and earlier Stangs is to get lower control arms with spherical bearings that allow for articulation of the suspension. that is why anyone who has really pushed a late model Mustang through a corner knows how the car will tend to do what racers call tail wagging.the tail wagging occurs when the suspension binds and then unloads causing unpredictable handling.Granatelli and J&M among others produce lower control arms with the spherical bearings that allow for smooth rotation of the suspension and much better handling.
