Construction & Design

The Cusco Steel Roll Cage is meticulously designed using high-quality cold-drawn seamless carbon steel tubing, which provides an excellent balance of strength and weight savings. The cage's design incorporates multiple mounting points and reinforcement bars to maximize rigidity and occupant protection. Advanced bending processing techniques allow for precise angles and seamless integration with the vehicle's interior, ensuring a clean and professional installation.

The TIG welding process used during manufacturing guarantees strong, consistent welds that contribute to the overall structural integrity of the cage. The design also considers ease of installation, with pre-drilled mounting points and compatibility with factory interior panels, making it accessible for both professional installers and experienced enthusiasts.

By pursuing weight reduction from the entire cage to the joints, Cusco ensures that the safety enhancements do not come at the expense of vehicle performance. The cage's robust construction also helps in minimizing chassis flex, which translates into improved handling and driver confidence during aggressive driving or racing scenarios.

Performance & Sound

While primarily focused on safety and structural integrity, the Cusco Steel Roll Cage also contributes to the overall chassis stiffness, which can enhance vehicle responsiveness and handling. The increased rigidity may result in a more precise steering feel and improved feedback, especially during high-speed cornering. Although it does not directly increase horsepower or torque, the added safety and chassis reinforcement support better performance in demanding driving conditions.

Installation of the cage may slightly alter the interior acoustics, but it generally does not produce significant noise or vibration. The primary benefit remains the enhanced safety and structural support for your Subaru WRX STI, making it an ideal upgrade for track days, autocross, or competitive racing.

Installation & Fitment

The Cusco Steel Roll Cage is designed as a bolt-in system that utilizes existing factory mounting points, ensuring a straightforward installation process. No cutting, drilling, or extensive modifications are typically required, although professional installation is recommended to ensure proper fitment and safety compliance. The cage is engineered to integrate seamlessly with the vehicle's interior, maintaining accessibility to essential components and interior panels.

Proper installation involves securing all mounting points according to Cusco's specifications, and in some cases, additional reinforcement or bracing may be recommended for extreme applications. It is essential to follow all installation instructions and local regulations when installing a roll cage for racing or street use.
