Xtreme-Grip™ Winning Combo

If you are comparing the best suspension system upgrades developed by pros specifically for your S197, look no further. These top performing Watts Link and Torque Arm Suspension system kits have been designed, optimized and proven in competition time and again.


Design Innovation, Xtreme-Grip™ Watts Link

CorteX Technology 4 Pivot Differential Cover Watts Link suspension system
  • Adjust stiffness
  • 4 pivot location points
  • Balance your front to rear grip

Lightest most durable suspension mod for your S197 tolerant of many ride heights.


Design Innovation, Xtreme-Grip™ Torque Arm

  • Unsurpassed corner exit
  • Significantly increase straight-line grip
  • Decrease front-end dive on braking

The Xtreme-Grip™ Torque Arm is a rear suspension component designed for the S197 to assign rear axle rotational loads closer to the center of gravity. These improvements are accomplished by changing the anti-squat and anti-lift geometry of the rear suspension.

Lowered Cars Need a Torque Arm

When a S197 Mustang is lowered from the factory ride height, the rear suspension geometry is compromised leading to reduced rear grip under acceleration. CorteX Suspension designs fix this and increase your grip.

About CorteX Racing

CorteX Racing (cortexracing.com) is a U.S. based engineering design house of performance aftermarket motorsports parts and customer car builds. CorteX was founded in 2009 when the public demand for their optimized prototype suspension components (raced on their own cars) delivered what both enthusiasts and professionals were after, an unmet need for quality, durability and results in Mustang aftermarket suspension.

The passion to innovate in motorsports has been lifelong for founder Filip Trojanek, a professional mechanical engineer experienced in aerospace, energy and automotive design.

Today, CorteX is an internationally recognized leader in vintage Pro-Touring and modern Muscle Car suspension systems. In 2019, CorteX expanded with a retail and automotive performance installation and fabrication shop in Ohio.

At CorteX, delivering “the core of performance” requires a precisely engineered suspension system to maximize grip and effectively transfer engine power to the road.
