Special Notes

Stifflers Convertible Rear Chassis Brace (’05-’14 Mustang)

Fitment / Vehicle Compatibility:

  • Designed specifically for the 2005-2014 Ford Mustang Convertible models (S197 generation, including GT, Shelby, Boss, etc.)

  • Ideal for owners seeking enhanced structural integrity when running with the top down.

Why This Brace Matters:
When you’re behind the wheel of a convertible Mustang, the lack of a fixed roof can mean compromised rigidity compared to coupes. The OEM rear chassis support brace (or absence thereof) often exhibited flexibility, corrosion issues, or was simply discontinued by the manufacturer. The Stifflers Convertible Rear Chassis Brace addresses that by adding meaningful structure and performance improvement for your convertible Mustang.

By installing this brace you’ll notice:

  • A firmer, more dependable ride when driving with the roof open or closed.

  • Improved response and chassis stability during hard launches, cornering, or spirited driving.

  • Reduced flex and body-twist, especially important for high-power or track-inspired builds.

Key Features & Benefits:

  • Direct integration into the lower control arm torque box for added structural support — engineered from the ground up for your S197 convertible. 

  • Sealed tubing construction, eliminating the common rust and corrosion issues associated with factory braces. 

  • Durable powder-coat finish for long-lasting good looks under the car. 

  • Enhanced suspension predictability, giving the driver more confidence behind the wheel. 

  • Precision-engineered for fitment and performance — each product design is test-fitted by Stifflers during R&D phase.

Technical Notes

Installation & Fitment Notes:

  • The brace system is designed for convertible Mustang models (‘05-’14) and integrates directly into the lower control arm torque box — ensure that your vehicle is in good condition and the mounting locations are intact.

  • Because the structure ties into the torque box, it’s important that the vehicle’s rear subframe and mount points are properly aligned and not compromised by previous collisions or poorly executed modifications.

  • For best results: pair this chassis brace with other suspension upgrades (rear sway bar, subframe connectors, quality bushings) for a more holistic chassis upgrade.

  • If you frequently track the car, launch hard, or run higher horsepower, this brace is a solid investment to reduce chassis fatigue and maintain performance.
