Description

The Stifflers Convertible Rear Chassis Brace (CRCB-M01) is engineered as a direct replacement for the original equipment brace on 2005-2014 Ford Mustang Convertible models, specifically the S197 generation including GT, Shelby, and Boss variants. The factory brace is known to be weak and prone to rust, making this aftermarket solution a crucial upgrade for enhancing chassis integrity. Constructed from durable mild steel tubing and finished with a resilient powder coating, this chassis brace is built to withstand the demands of performance driving and to provide long-term protection against the elements. Its sealed tubing design ensures longevity, unlike the discontinued OEM part. By upgrading to the Stifflers Convertible Rear Chassis Brace, owners can expect a significant improvement in chassis stiffness. This enhanced rigidity leads to a firmer, more dependable ride quality and sharper handling characteristics, allowing the car's suspension to perform more effectively. The installation process is estimated to take 1.5 hours, with specific torque values provided for the front bolts and control arm bolt.
