This is a true front and rear coil over system featuring CorteX Proprietary valving with JRi dampers.

 

These struts and shocks include all the geometry advantages of our other competition struts.  Now they are available with the advantages of JRi damper technology. See options below for fitment 10.5-11 in wide from wheels and 315mm tires.

 

CorteX Racing has developed Mustang-specific line of coil-overs based on years of street driving 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.

Bullet proof steel housing and mounting brackets off more tire clearance and reduced weight than 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.

This system includes:

Front:

  • Struts Assembly with Single Adjustable JRi Internals (pair)
  • Camber Plate (pair)
  • Choice of Springs
  • All mounting hardware to complete the installation

Rear:

  • JRi Single Adjustable dampers
  • Springs and appropriate valving
  • Coil over hardware
  • Mounting brackets and hardware

The JRI piston’s lower cross-section and reduced port length improves overall dynamic performance. These features coupled with JRI’s precise flow metering increase the hydraulic stiffness of the strut and improve its overall response. With its unique piston design, innovative components like the extension cage, and meticulous attention to sealing any unintended bleed paths, JRI struts have less hysteresis than competing manufacturer’s struts. The proprietary bearing carrier isolates side loads associated with misalignment that occur in normal strut operation. This is especially important with weight transfer. By design, more energy is dissipated through the fluid and NOT through the friction of the components. The JRI strut’s low friction seal design has less stick-slip than other leading strut manufacturers. The result is lower dynamic force and lower effective rate influencing your setup. This added adjustment feature allows the struts to not only adjust high speed extension, but also to adjust low speed compression or extension through the shaft.

    I recently installed the Cortex track watts link and coilover system with JRi single adjustable dampers on my 2007 Mustang GT and it brought my car up to an entirely new level. As soon as I opened the package, I knew this was something special. The quality of workmanship is immediately evident, from the welds to the finish. After installation and proper corner balancing, I ran the car at two different track days in the same week. This is where your system really shines. The car is eager to tackle any bends. The JRi dampers easily coped with any uneven track surfaces and the car remained perfectly level and composed. Turn-in is immediate and corner exit is predictable and easy to control at the limit of adhesion. Rebound was instantaneous without upsetting the car’s balance. I was able to overtake brand new BMW M cars, new Mustangs, easily surpass Miatas and Subarus, and even keep pace with an Audi R8, all thanks to the confidence-inspiring Cortex suspension. My Mustang simply wanted more and continued to perform lap after lap! Thanks again for a great product!
