As I mentioned before, I found out about this car after seeing a post on CorteX Racing’s Facebook page as the car was being assembled. CorteX is a suspension manufacturer that creates some rather trick stuff for the S197 chassis. Starting at the rear, the OEM three-link was discarded in favor of CorteX Racing’s Torque Arm and Watts Link setup. The torque arm eliminates the need for the upper 3rd link that Ford uses. This improves straight-line and off-corner bite while also improving the roll steer of the live rear axle.
The front pivot point is just after the front joint of the driveshaft and is on its own bracket.
It also features a grease nipple for maintenance.
The rear lower control arms are adjustable for length and the pivot points are relocated via brackets to improve the anti-squat geometry for the lowered ride height.
You’re probably looking at that other bar where the factory Panhard bar once was and thinking, “why is there a track link still there if they are using a CorteX Watts Link?” Well, that’s not what that bar is doing. Instead, it's a brace to strengthen the mounts for the Watts Link.
The Watts Link cover is designed with the provisions for oil cooler lines and a temperature sensor from CorteX Racing.
The K&N RTR uses JRi dampers front and rear along with Eibach tender and main Springs. The JRi dampers are adjustable for bound and rebound along with ride height in a coil over setup and feature remote reservoirs.
The front of the car’s suspension features some very interesting parts from CorteX as well. The OEM Mustang uses MacPherson struts, but CorteX supplied their Short-Long Arm suspension conversion to be used instead. This gives the K&N Mustang RTR improved camber gain and more stable roll center geometry over the OEM struts along with higher strength thanks to tubular construction. It provides far more adjustability than the strut setup since both the upper and lower arms are adjustable. CorteX also provided their Radial-X competition uprights and hubs for the SLA conversion. By the way, this is all a bolt on conversion and none of the CorteX parts are welded on.
