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

A rear strut bar connects the upper mounting points of your rear shock absorbers. This helps to stiffen the car's chassis, reducing flex during cornering. The result is a more direct steering feel and improved stability when the car is under load.

Is this strut bar difficult to install?

This Cusco strut bar is designed as a direct bolt-on part. It attaches to the factory strut tower mounting locations, so typically no modifications or specialized tools are required for installation.

What does 'OS' mean in the product name?

OS stands for 'Over-Steering'. In this context, it refers to a specific design of the strut bar that is often wider or shaped differently than standard bars, intended to provide more effective chassis bracing.

Product Details

Cusco is well-known for making solid suspension components, and this OS (Over-Steering) Rear Strut Bar is a great example of their work for your Subaru BRZ, Scion FR-S, or Toyota 86. This bar connects the upper strut towers in the rear of your car, helping to stiffen the chassis. When you're cornering, especially at higher speeds or on a track, the chassis can flex. By tying the strut towers together, this bar reduces that flex, which can lead to a more direct and responsive feel from the rear suspension.

This strut bar is built with a strong steel construction, designed to handle the stresses of spirited driving. The OS design is a bit wider than some other bars, which can offer a more substantial bracing effect. Installation is typically straightforward, bolting directly to the existing strut tower mounting points. You'll notice a difference in how the car handles transitions and maintains stability under load.

If you're looking to get more out of your BRZ, FR-S, or 86's handling, especially if you've already upgraded your suspension or tires, this Cusco strut bar is a popular choice for improving chassis response.
