The Cusco Type-40 Rear Strut Brace is a high-performance chassis reinforcement component designed specifically for Honda Civic models from 2011 to 2025 and the CR-X variants. Crafted from lightweight yet durable aluminum, this rear strut brace enhances the structural rigidity of your vehicle's chassis, helping to reduce flex and improve handling during spirited driving or track days.

Key Features

The Cusco Type-40 Rear Strut Brace incorporates several advanced features that set it apart from standard chassis reinforcements:

• Heavy-Duty Aluminum Construction: The 40mm OD hollow aluminum cross section provides excellent rigidity while keeping weight to a minimum, ensuring enhanced chassis support without compromising vehicle performance.
• Billet Aluminum Solid Ends: Welded billet aluminum ends offer robust attachment points that withstand harsh driving conditions and chassis flex, maintaining structural integrity over time.
• Flawless Fitment: Aluminum end plate brackets, painted in a titanium gray color, are precisely engineered for each specific vehicle application, ensuring a perfect fit and seamless integration with your vehicle's existing suspension components.
• Simple Installation: Designed for straightforward bolt-on installation, the strut brace requires no cutting or drilling, allowing you to upgrade your chassis quickly and easily with basic tools.
• Enhanced Rigidity and Handling: By connecting the rear strut towers, this brace significantly reduces chassis flex, translating to improved handling, sharper steering response, and increased driver confidence during aggressive maneuvers.
• Versatile Compatibility: Available in three different center bar types tailored to specific applications, ensuring optimal fitment and performance for your vehicle setup.

Construction & Design

The Cusco Type-40 Rear Strut Brace is meticulously designed with a focus on durability and performance. Its lightweight hollow aluminum tubing features a 40mm outer diameter, providing a perfect balance between strength and weight savings. The welded billet aluminum ends are CNC-machined for precise fitment and durability, ensuring that the brace maintains its structural integrity even under demanding driving conditions. The titanium gray painted brackets are not only aesthetically appealing but also resistant to corrosion, maintaining their appearance over time. This combination of materials and craftsmanship results in a chassis reinforcement component that enhances vehicle stiffness, improves handling response, and contributes to a more confident driving experience.

Performance & Sound

While the Cusco Type-40 Rear Strut Brace primarily focuses on chassis reinforcement and handling improvements, users often report a more connected and responsive feel during cornering and spirited driving. The increased rigidity reduces body flex, allowing your suspension to work more effectively and providing a more precise steering response. This upgrade does not significantly alter vehicle sound but contributes to a more solid and planted chassis feel, especially noticeable during aggressive driving or track use.

Installation & Fitment

The Cusco Type-40 Rear Strut Brace is designed for a straightforward bolt-on installation. It mounts directly to the rear strut towers using the included brackets and hardware, with no cutting, drilling, or complex modifications required. The precise fitment ensures a secure and stable connection, allowing you to complete the installation in under an hour with basic hand tools. This ease of installation makes it an ideal upgrade for enthusiasts looking to improve chassis stiffness without extensive mechanical work.
