Front Suspension with Radial-X Optimization

Competitor’s systems that utilize Corvette Spindles compromise the suspension geometry. While  C5/C6 Corvette spindles are inexpensive, they compromise the suspension geometry and are intended for cars with a much lower center of gravity and different engine location relative to the steering rack.



A New Class of Performance

This system will provide the handling needed to run down supercars.


Coilover Options * 

All Coilovers come as a complete pair with springs and hardware.

Brake Systems (Include Caliper Brackets) *

Xtreme-Grip Vintage Radial-X Front Suspension System

Vehicles: Ford Mustang (1967- 1970) and Mercury Cougar (1967- 1970)

This version, featuring our premium billet Radial-X spindles, is a zero-compromise front suspension upgrade solution for those who want the highest quality and best-engineered components on their vehicles.

Modern Geometry, Pro Touring Upgrade

A complete redesign and utilizes modern geometry that is suited for today’s performance tires.

If you’ve ever driven a vintage mustang and shared the road with modern cars you understand that it can be a white knuckle ride. Even with standard aftermarket improvements that are readily available the steering is sloppy, vague, and unresponsive to driver inputs. With the investment required to buy and maintain a vintage mustang these days, we feel it make sense to spend a small percentage of the total vehicle value toward excellent handling. There numerous front suspension systems on the market that are based on the OEM Ford geometry and they just do not measure up to CorteX’s standards.  That is why we went through the trouble of re-engineering everything on both the front and rear suspension to offer customers a complete system that is capable of supercar levels of handling and control.

The OEM shocks tower can either remain in place for an OEM underhood appearance or be trimmed/removed.

Lower + Optimized with Radial-X™ 

The CorteX exclusive Radial-X spindles allow the chassis to be lower to obscene ride height yet retain excellent suspension geometry, with the ability to fit modern large performance tires.

With that said, these spindles are also capable of street-worthy ride height when needed. Competitor’s systems that utilize the less expensive C5/C6 Corvette Spindles compromise the suspension geometry and are intended for cars with a much lower center of gravity and different engine location relative to the steering rack.

Radial-X Spindle Option


Stiffer Stronger Chassis

We engineered our suspension to increase chassis strength and stiffness for superior response.  The geometry optimizes the roll center height, lateral roll center migration, and minimizes bumpsteer all the while allowing the build to adjust ride height as much as 2.5 inches to achieve the optimal stance both at the track and on the street.

Stock vintage Mustangs have lightweight flimsy unibody chassis that can compromise handling.

Other systems require the car to be completely cut up for installation which makes the vehicle even flimsier than it was from the factory while adding additional weight in the process.

Easy Install with Minimal Mods

The CorteX Xtreme-Grip Vintage Suspension System is designed for easy installation with minimal permanent modifications to your pony.  In fact, it is even possible to install the complete front suspension and retain the OEM shock towers for a factory underhood appearance.
