The CorteX Watts Link complete kit replaces the panhard bar in a few simple bolt-on steps.
 
What makes this ideal for track racing?
The CorteX “Track” watts link system has a spherical bearing at all pivot points to minimize friction and deflection.
Four possible pivot location points of the center pivot.  The pivot point of a watts link is the rotation center of the rear of the vehicle. Moving it up or down relative to the center of gravity of the vehicle allows the roll stiffness of the suspension to change. This enables balancing the front-to-rear grip of the vehicle so that the desired handling can be achieved.
Adding a CorteX Watts Link to your mustang will take your racing to a whole new level. 
Say goodbye to the nervousness you feel at the rear of your car near its cornering limits, so you can focus on turning your mustang into a supercar killer.
