Overview

The Cusco Strut Brace Type-OS Front with Brake Cylinder Stopper is a high-performance chassis reinforcement component designed specifically for Mitsubishi Lancer Evolution models 7, 8, and 9 (CT9A). Crafted to enhance the structural rigidity of your vehicle's front suspension, this strut bar helps improve handling response, steering precision, and overall stability during spirited driving or track days. Whether you're a performance enthusiast or a dedicated tuner, this strut brace provides a significant upgrade over the factory chassis bracing, ensuring your Evo maintains optimal alignment and reduces flex under demanding conditions.

Engineered with both form and function in mind, the Type-OS (Oval Shaft) center bar combines lightweight construction with exceptional strength. Its stylish oval cross-section not only adds a distinctive aesthetic touch to your engine bay but also contributes to the overall durability and performance of the brace. The inclusion of a brake cylinder stopper further enhances the chassis stiffness, helping to minimize flex during aggressive braking and cornering, which translates into more precise control and confidence behind the wheel.

Key Features

The Cusco Type-OS Front Strut Brace is packed with features that cater to both performance and durability:

• Lightweight Aluminum Construction: The oval-shaped shaft is made from high-quality aluminum, striking a perfect balance between lightweight design and structural integrity. This ensures minimal added weight while maximizing strength.
• Engineered Inside and Out: The internal design of the piping is optimized for strength-to-weight ratio, providing a robust reinforcement without unnecessary bulk.
• Stylish Design: The oval cross-section not only improves aesthetics but also enhances the overall rigidity of the bar, reducing flex and improving handling response.
• Precision Fitment: Steel end plate brackets, painted in Cusco's signature blue, guarantee flawless fitment tailored to the specific vehicle application, ensuring easy installation and reliable performance.
• Application-Specific Bar Shapes: Three different center bar types are available, each designed to match the unique chassis geometry of the Evo 7/8/9, providing optimal fit and performance.
• Simple Bolt-On Installation: Most installations are straightforward, requiring only basic tools and no modifications to the vehicle. The design allows for quick and secure mounting to the factory mounting points.
• Brake Cylinder Stopper: Integrated to reinforce the front chassis, this feature helps reduce flex during aggressive braking, contributing to improved pedal feel and stability.

Construction & Design

The Cusco Strut Brace Type-OS features a meticulously engineered oval shaft made from lightweight aluminum, which offers a sleek appearance and excellent durability. The internal structure is designed to provide maximum strength while keeping weight to a minimum, ensuring that your vehicle's performance is enhanced without sacrificing agility. The steel end plates are precisely machined and painted in Cusco's iconic blue, ensuring a perfect fit and long-lasting corrosion resistance. The overall design emphasizes ease of installation, durability, and aesthetic appeal, making it an ideal upgrade for enthusiasts seeking to improve their Evo's chassis stiffness and handling characteristics.

Performance & Sound

While primarily focused on chassis reinforcement, the Cusco Type-OS Front Strut Brace contributes to improved handling response and steering feel. By reducing front-end flex, it allows your suspension to work more effectively, translating into sharper turn-in and more predictable handling. Although it does not produce a noticeable sound, the increased rigidity can result in a firmer, more connected driving experience, especially during aggressive cornering or high-speed maneuvers.

Installation & Fitment

The Cusco Strut Brace Type-OS is designed for a straightforward bolt-on installation. It mounts directly to the factory strut towers using the included brackets and hardware, requiring no cutting, drilling, or modifications to your vehicle. The process typically involves removing the existing strut bar and replacing it with the Cusco unit, making it accessible even for DIY enthusiasts with basic tools. The precise fitment ensures that the brace aligns perfectly with the chassis, providing maximum reinforcement and stability.
