CorteX Xtreme-Grip Watts Link System, Street (CWL-40-2000S) - 2005-2014 Ford Mustang
Improve rear axle control and handling consistency on your 2005-2014 Ford Mustang with the CorteX Racing Xtreme-Grip Street Watts Link System. Designed to replace the factory-style panhard bar arrangement on solid rear axle Mustangs, this system keeps the rear axle more consistently centered as the suspension moves through its travel and helps the car behave more symmetrically in left and right-hand corners.
The Street version uses polyurethane bushings at the chassis pivot connection to reduce noise, vibration, and harshness while retaining the performance advantages of the Watts link design. With four available center pivot positions, the rear roll center can be adjusted to fine-tune rear roll stiffness and help balance front-to-rear grip for the driver's preferred handling characteristics.

Why Upgrade to a Watts Link?
A panhard bar controls side-to-side axle movement but also moves the axle through an arc as the suspension compresses and rebounds. This means the rear axle can shift laterally during suspension travel. A Watts linkage more closely approximates straight vertical axle movement by using a central pivot point, helping maintain more consistent rear axle position and suspension behavior.
The result is improved chassis balance and more predictable handling, especially when transitioning between left and right-hand corners.
Adjustable Rear Roll Center
The CorteX system provides four possible center pivot positions. Raising or lowering the pivot relative to the vehicle's center of gravity changes the effective rear roll center and suspension roll stiffness. This gives the driver another tuning tool for balancing front and rear grip and refining the Mustang's handling characteristics.
Street Configuration
The CWL-40-2000S Street system uses polyurethane bushings at the chassis pivot connection to minimize noise, vibration, and harshness. This makes it a better fit for street-driven performance Mustangs that still need precise rear axle control.
CorteX also offers a Track version, part number CWL-40-2000, which uses spherical bearings at all pivot points to further reduce friction and deflection.
