CorteX Racing JRI Single Adjustable Coil-Over System Mustang 2005-2014

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. Chose the Offset Strut option for fitment of 10.5-11 inch-wide wheels and 315mm tires.

This system includes:


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


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


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 with 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.

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 your Ford Mustang to the next level of performance.
