CorteX Double A-Arm SLA Front Suspension System with Radial X Spindles, Street (FSS-40-1000) - 2005-2014 Ford Mustang
Transform the front suspension of your 2005-2014 S197 Mustang with the CorteX Racing Double A-Arm SLA Front Suspension System. Designed as a complete short-long arm conversion, this system replaces the factory strut-based layout with a double-wishbone design that provides improved camber gain, more stable roll center behavior, additional tire clearance, and greater suspension consistency under hard driving.
The Street version is engineered to retain compatibility with the OEM steering rack, including hydraulic and EPAS configurations, and is not designed around Mustang II, Fox Body, or SN95 steering racks. CorteX also offers an EPAS retrofit option for 2005-2010 cars when desired.
Due to the custom nature of these kits, we encourage you to call to order. We will work with you to determine the proper shocks, brake system, and steering rack system for your setup.

Why Upgrade to an SLA Suspension?
A properly designed short-long arm suspension provides geometry advantages that are difficult to achieve with a conventional MacPherson strut layout. By controlling the upper and lower control arms independently, the suspension can gain negative camber more effectively during compression while keeping the roll center more stable both vertically and laterally.
This allows the tire to maintain a better contact patch during cornering and can reduce the amount of static negative camber required for performance use. CorteX states that back-to-back testing has shown lap time improvements of approximately 2 to 4 seconds depending on track length and layout when using the same tires.
Improved Ride Height Sensitivity
The CorteX SLA geometry is substantially less sensitive to ride height changes than a traditional strut setup. For example, lowering the chassis approximately one inch causes the roll center to move by roughly the same amount instead of creating the larger geometry shifts that can occur with strut-based suspensions.
Competitive Design Advantages
- Designed for quicker and easier installation than many custom SLA conversions
- Retains use of the more advanced OEM Mustang steering rack
- Compatible with electronic power assist steering where applicable
- Uses a stiff and adjustable spindle/hub assembly with integrated wheel speed sensor provisions
- Feeds spring and damper loads into the OEM shock tower load-bearing location
- Reduces unwanted chassis deflection compared to systems that relocate loads away from factory structural points
- Strong, rigid K-member, shock mounts, and control arms
- Supports a wide range of damper and brake configurations
- Allows roll center adjustment
Radial X Street Spindles
The included Radial X Street spindles provide the foundation for the CorteX SLA geometry while maintaining compatibility with street-oriented applications. The spindle and hub arrangement is designed to provide strength, stiffness, adjustment capability, and integration with factory-style wheel speed sensing.
