Xtreme-Grip™ Coil-Over System CorteX JRi Single Adjustable 2015-2020 Mustang S550, GT350, Non Coilover Rear

This system features coilover front struts and non-coilover rear shocks including CorteX Proprietary valving with the JRi dampers.

CorteX Racing has optmized our Mustang-specific line of coilovers using professional engineering and years of street and track testing.

This coil-over system apply race-winning technology to your vehicle by providing precision chassis control, ride height and geometry alignment. Installation is straightforward as coil-over hardware, springs, and all mounting brackets are included. With longevity and performance as priorities, all components use high-grade materials ideal for the application with durable finishes. Damper valving has been optimized and will take you to the next level of performance.

Geometry Advantage of Competition Struts

These struts and shocks include all the geometry advantages of our other competition struts such as the ability to fit 10.5-11 in wide from wheels and 315mm tires with the offset strut option.

CorteX Racing has developed Mustang-specific line of coilovers based on years of street driving and track testing.

• Precision chassis control
• Ride height and geometry alignment
• Easy Install, all components included
• High-grade materials ideal for the application with durable finishes

*Shipping times may vary based on stock status and/or level of customization, if any. Contact us and we are glad to help with more specifics on your product.

Vehicles: Ford Mustang S550, Shelby GT350, GT350R (2015 -2019)

The non-coilover rear is intended for applications that require an OEM rear spring and damper arrangement such as certain SCCA SOLO classes and individuals seeking to limit the number of point add in Time Trials.

Proven Quality and Durability

CorteX coilover struts housing and shock mounts are some of the most rigorously tested components in the industry. As former structural analysis engineers, we understand strength, deflection, and fatigue and how they apply to mechanisms such as suspension systems. Every component we see undergoes both computer simulated finite element modeling as well as confirmation with real life testing. Purchase with confidence knowing you are getting the highest quality products possible with the most value.

Top Performing Design

Our strut housings and mounting brackets are built of bulletproof steel which offers more tire clearance and reduced weight compared to bulkier aluminum components. Since struts see significant bending loads (unlike shocks which are mostly limited to tension and compression loads) stiffness of the housing is essential in order to minimize camber loss and prevent bending and component damage in the event accidental abuse from contact or an off-track excursion. Engineers know that aluminum deflects 3 times more than steel however it is also 1/3 the weight. What this means is that if you are designing a component for stiffness the aluminum needs to be 3 times thicker to have the equivalent stiffness of the steel parts. With that knowledge, it is easy to deduct that no weight will be saved by using aluminum in the design. Steel also has superior fatigue properties than aluminum which means that it can be loaded closer to its limits over time (cycles) without fatigue failures. Aluminum, in contrast, must be kept further below its load limits to avoid fatigue failure. That is the exact reason that lightweight airplane components are replaced on a predetermined schedule since the engineers know how long the aluminum parts can safely be kept in service before a fatigue failure is likely to occur.
