Cusco Rear Trunk Power Brace

2003–2006 Mitsubishi Lancer Evolution VIII / IX

Part #: 564 492 RT

Overview

The Cusco Rear Trunk Power Brace is a high-performance chassis reinforcement component designed specifically for Mitsubishi Lancer Evolution VIII and IX models from 2003 to 2006. Developed by Cusco's team of chassis engineers, this power brace is engineered to enhance the structural rigidity of your vehicle's rear section, providing a significant reduction in body flex during spirited driving and cornering. Whether you're a performance enthusiast, track day participant, or someone seeking improved handling and stability, this bolt-on reinforcement offers a reliable upgrade that complements your vehicle's existing chassis architecture.

By reinforcing the rear trunk area, the Cusco Power Brace helps maintain optimal suspension geometry under load, resulting in more precise steering response, improved cornering stability, and enhanced overall driving confidence. Its design ensures that your Mitsubishi Evo maintains its structural integrity during aggressive maneuvers, translating to better control and a more connected driving experience.

Key Features

The Cusco Rear Trunk Power Brace incorporates several advanced features to deliver maximum chassis reinforcement and durability:

• Constructed from high-strength steel with a durable finish to withstand harsh conditions and ensure long-lasting performance.
• Designed with precision based on extensive motorsports data logging, ensuring an exact fit and effective reinforcement.
• Bolt-on installation process that requires minimal body trimming, typically involving minor modifications to interior or under-cover panels for a clean, OEM-like appearance.
• Minimizes body flex at the rear during high-load cornering, helping to preserve suspension geometry and improve handling response.
• Acts similarly to stitch welding a chassis, providing a significant increase in structural rigidity without permanent modifications.
• Compatible with other chassis reinforcement components for a comprehensive handling upgrade.
• Designed specifically for the Mitsubishi EVO VIII and IX, ensuring perfect fitment and seamless integration with factory components.

Construction & Design

The Cusco Rear Trunk Power Brace is crafted from high-quality steel, ensuring strength and durability under demanding driving conditions. Its design features a precisely engineered bar that spans the rear trunk area, connecting key structural points to distribute loads evenly and reduce flex. The bolt-on nature of the brace allows for straightforward installation, with minimal body trimming required to achieve a clean, professional look. The use of CAD-developed components ensures a perfect fit, while the robust construction guarantees long-term performance and resistance to corrosion.

This reinforcement effectively stiffens the chassis, similar to stitch welding, but without the need for permanent modifications. The result is a more rigid rear structure that enhances handling, stability, and driver confidence during aggressive driving or track use.

Performance & Sound

While the Cusco Rear Trunk Power Brace primarily focuses on chassis reinforcement, its impact on vehicle handling is significant. By reducing body flex, it helps maintain suspension alignment and improves steering response, especially during high-speed cornering. This leads to a more predictable and confident driving experience. Although it does not directly increase horsepower or torque, the improved chassis stiffness allows your vehicle's suspension to perform at its best, translating to better overall performance on the road or track.

Installation & Fitment

The Cusco Rear Trunk Power Brace is designed for a bolt-on installation that can typically be completed with basic hand tools. The process involves removing interior panels or under-cover components to access mounting points, then securing the brace with the included hardware. No cutting, drilling, or extensive body modifications are required, making it a convenient upgrade for enthusiasts and professional installers alike. The reinforcement is engineered to fit perfectly within the factory chassis architecture, ensuring a seamless integration that maintains the vehicle's original appearance and structural integrity.
