Description

The CUSCO Rear Strut Bar with Φ40 Carbon Shaft represents the pinnacle of lightweight, high-strength chassis reinforcement technology. Utilizing an ultra-lightweight, high-strength Φ40 carbon fiber pipe as its core structure, this strut bar delivers exceptional torsional rigidity and vibration damping while minimizing added mass. Designed to significantly enhance rear-end stability and chassis balance, it features titanium-colored mounting brackets and requires professional interior modification for optimal, integrated installation.

Product Highlights

🏗️ Ultra-Lightweight Φ40 Carbon Fiber Construction
Features a Φ40mm high-strength carbon fiber pipe as the primary structural element, providing an exceptional strength-to-weight ratio. This advanced material delivers maximum rigidity with minimal weight addition, optimizing chassis performance without penalty.

⚖️ Maximum Rear Chassis Stiffness & Control
The large-diameter carbon shaft creates an extremely rigid connection between the rear strut towers, drastically reducing chassis flex during aggressive cornering, acceleration, and braking. This results in superior rear-end stability, improved traction, and a more neutral, predictable handling balance.

🎨 Premium Aesthetic & Finish

• Φ40 Carbon Shaft: Sleek, high-tech appearance with visible carbon weave, showcasing its performance pedigree.

• Titanium-Colored Mounting Brackets: Durable, corrosion-resistant finish that complements the carbon fiber for a cohesive, high-end look.

🔧 Interior Modification Required for Optimal Integration
To ensure a secure, direct connection to the vehicle’s chassis and maximize performance, interior cutting/modification is required to properly mount the bar and its brackets.

⏱️ Streamlined Mechanical Installation
Once interior modifications are completed, the mechanical installation is efficient with an estimated time of 1.0 hour, allowing for a straightforward process by experienced technicians.

Installation & Performance Notes

⚠️ Professional Installation Mandatory
Due to the required interior modification and the critical need for precise alignment and torque on the carbon components, installation must be performed by a qualified technician with expertise in interior trim and high-performance chassis systems.

🏁 Engineered for Competition & High-Performance Use
An essential upgrade for track-focused builds, time attack vehicles, and drivers who demand the highest level of chassis feedback, stability, and weight optimization. Ideal for competitive environments where every gram and every percent of rigidity counts.

🔗 Complete the System for Ultimate Balance
For a fully optimized chassis, pair this rear carbon strut bar with a CUSCO front strut bar (such as a matching carbon or S-MCB model) to achieve comprehensive stiffness, sharpened steering response, and ultimate driver confidence.
