Designed with durability and performance in mind, it helps your Mitsubishi Evo deliver its full potential on both the street and the track.

Key Features

The Cusco Lower Arm Bar Ver.2 Front incorporates several advanced features to maximize chassis stiffness and driving performance:

• Constructed from high-strength steel with a solid truss structure, providing exceptional rigidity and durability.
• Multiple mounting points at the base of the suspension increase vertical and horizontal body stiffness, effectively reducing chassis flex.
• Designed to connect the left and right lower arm mounting points, creating a more unified and stable chassis framework.
• Engineered to improve transmission efficiency, resulting in sharper steering response and enhanced traction during hard cornering.
• Easy bolt-on installation using factory mounting points, with no need for modifications or cutting.
• Manufactured by Cusco, a trusted name in motorsport and performance suspension components, ensuring quality and reliability.

Construction & Design

The Cusco Lower Arm Bar Ver.2 Front features a robust design utilizing high-quality steel tubing and a solid truss structure. The component is precisely engineered through CAD development to ensure perfect fitment and maximum effectiveness. Its multi-point mounting system reinforces the suspension's base, significantly increasing chassis stiffness without adding unnecessary weight. The design also promotes better load distribution across the suspension components, reducing stress and wear over time. TIG welding ensures strong, clean joints that withstand rigorous driving conditions, making this upgrade both reliable and long-lasting.

Performance & Sound

By increasing the rigidity of the chassis at critical suspension points, the Cusco Lower Arm Bar Ver.2 Front helps improve overall handling performance. Drivers will notice more responsive steering, reduced body roll, and enhanced stability during aggressive maneuvers. While this component does not directly increase horsepower or torque, it optimizes the vehicle's suspension response, allowing your Evo to perform more effectively on twisty roads or race tracks. The installation results in a more planted feel and improved driver confidence, especially in high-speed cornering.
