Xtreme-Grip Watts Link System, 2005-2014 S197 Mustang, Street

Rated 5.00 out of 5 based on 3 customer ratings

SKU: CWL-40-2000S

A watts linkage locates the rear axle laterally, meaning it prevents relative sideways motion between the axle and body of the car. It is an improvement over a panhard bar because the watts link more closely approximates vertical straight-line motion of the axle assembly allowing the vehicle to behave symmetrically in left and right hand corners.  You can expect:


  • Improve dynamic stability
  • Increase cornering grip
  • Ability to tune front/rear balance of vehicle
  • Less lateral tire movement allowing larger tire fitment




Xtreme-Grip Watts Link System, Street – 2005-2014 S197 Mustang

The watts link replaces the panhard bar in a few simple bolt-on steps. What makes the CorteX Xtreme-Grip watts link so affective is the 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 be change. This enables balancing the front-to-rear grip of the vehicle so that the desired handling can be achieved.

Two models of the watts link are available for the 2005-2014 Mustangs: Street or Track

The street system utilizes poly bushings on the chassis pivot connection to minimize noise, vibration, and harshness (NVH).

The track system has spherical bearing at all pivot points to minimize friction and deflection.

The watts link is ideally pair with our coil over systems and with the optional adjustable front anti roll bar, ARB-40-1003.

    An absolute MUST for every Mustang owner who doesnt “grocery get” their car. This improves the stability that is required from daily driven street use to all out track use, period.

    Well engineered and works as stated. Gives that IRS feel by removing the rear end wobble of the stock panhard bar set-up. Will add additional noise transfer due to the solid mounting even when using the street version, fyi. Make sure you have a wide range of calibrated accurate torque wrenches as they state in the directions. This modification was made AFTER I replaced the springs, struts/shocks and rear lower control arms. Do that first and in steps so you know how each modification changes your car and your driving experience.

    Amazing! I ordered the double sided rod end version but received the Poly/Rod. Honestly I’m kind of glad because I actually have less noise then my previous setup with the aftermarket panhard bar I was using. I had to replace my Whiteline sway bar because it will not work with this Watts. I was not impressed with Whiteline products. You get what you pay for. Spend the extra money…
