Cusco Strut Bar OS Front NA-NB Miata

The Cusco OS (Over-Steering) strut bar is built from a strong, 40mm steel tube, which is notably thicker than many standard bars. This beefier construction is key to its function: reinforcing the front strut towers on your 1990-1997 or 1999-2005 Mazda Miata. By tying these towers together, the bar helps reduce chassis flex during hard cornering, keeping your suspension geometry more consistent.

When you're pushing your Miata through turns, the chassis can twist slightly. This flex can make the steering feel a bit vague or less responsive. The Cusco OS strut bar combats this by providing a solid link between the tops of the front suspension. You'll notice a more direct feel through the steering wheel and a flatter cornering attitude, making the car feel more planted and predictable when you're driving it hard.

This is a popular upgrade for Miata owners looking to get more out of their car's handling. It's designed as a direct fit for the specified Miata models, making installation straightforward for most DIYers. You'll be able to feel the difference in how the car handles quick transitions and sustained cornering.
