MISHIMOTO Ford Fiesta ST Trunk Brace, 2014-2019

The Mishimoto Trunk Brace enhances chassis rigidity and improves handling performance for the 2014–2019 Ford Fiesta ST. Constructed from rigid 14‑gauge steel with CNC‑machined steel end plates, the brace reinforces the rear structure of the vehicle to reduce chassis flex during cornering. The result is improved steering response and a more planted rear end, whether on the street, in autocross, or during track sessions.

Despite its structural benefits, the brace occupies minimal cargo space and retains full use of the factory false floor, preserving the practicality of the Fiesta ST’s hatchback layout. Installation is straightforward, and the durable steel construction ensures long‑term reliability. As with all Mishimoto Fiesta ST components, the trunk brace is backed by the Mishimoto Lifetime Warranty.
