A complete redesign utilizing modern geometry
Particular consideration was given to packaging, weight, and suspension geometry for the vintage mustang platform. The leaf springs suspension was discarded in favor of a watts link, torque arm, and Coilover package which does everything better than the original suspension.
Feel the reduction of unsprung weight and friction.
Rear grip is exponentially improved and power is put down effortlessly both in a straight line and coming off of corners. The torque arm serves double duty and also virtually eliminates nose-dive under braking. Instead, the entire chassis squats as the deceleration loads push the entire car into the pavement at its center of gravity. If you’ve never driven a car with a well-designed watts link/ torque arm combination be prepared for a revelation. You won’t go back to anything else!
Easy install with minimal alteration to your Mustang
The CorteX Xtreme-Grip Vintage Suspension System is designed to install with minimal permanent modifications to your pony.
To install, the only permanent modifications required are the weld-in subframe connectors and a simple modification to the rear trunk sheet metal just ahead of the gas tank to gain adequate clearance for the watts link and coil-overs. Rest assured, all modifications for a CorteX build can be reversed at a later time if desired.
A Vintage Mustang has a lightweight flimsy unibody chassis that can compromise handling; as a result, when other suspensions systems require the car to be completely cut up during installation… but, this actually makes the vehicle even flimsier than factory original while adding additional weight in the process.
Increase chassis strength and stiffness
The engineers at CorteX designed the Watts Link System to optimize superior responsiveness and durability using professional engineering and testing methods.
