What is the main benefit of installing this rear strut bar?

This strut bar connects the upper mounting points of your rear suspension. By doing so, it stiffens the chassis, reducing body flex during cornering and leading to more predictable handling.

Does this strut bar come with all the necessary hardware for installation?

This strut bar is designed to replace the OEM bar and utilizes the factory mounting points. You will typically reuse the original hardware unless otherwise specified by the manufacturer's instructions.

What is the difference between this 'OS' bar and a standard strut bar?

The 'OS' in the name stands for Over-Steering, indicating a larger diameter bar. This larger diameter is intended to provide increased chassis stiffness and a more significant improvement in handling compared to smaller, standard-sized bars.

Product Details

When you're pushing your 2006-2011 Honda Civic Si through corners, you want the chassis to feel solid and responsive. This Cusco OS (Over-Steering) rear strut bar is designed to connect the upper mounting points of your rear suspension, tying the chassis together and reducing flex. By stiffening the body, it helps maintain proper suspension geometry under load, leading to more predictable handling and a more connected feel to the road.

Cusco is well-known for its performance suspension components, and this strut bar is a well-built piece designed to replace the factory bar. It's constructed from strong aluminum with steel mounting brackets, offering a good balance of rigidity and weight savings. The larger diameter bar is intended to provide a more noticeable improvement in chassis stiffness compared to smaller bars. Installation involves bolting directly to the existing strut tower mounts, making it a straightforward upgrade for those looking to enhance their Civic Si's handling characteristics.
