Product Description

The **Cusco 429 540 AT Front OS Strut Tower Brace** is a performance-oriented chassis reinforcement part engineered specifically for the **Mazda MX-5 (ND)** platform from 2016 through 2022. This Type OS (Oval Shaft) brace connects the front strut towers, reducing flex and helping preserve correct suspension geometry under hard cornering and spirited driving, resulting in sharper steering feel and improved stability.

Constructed with a lightweight aluminum oval main bar and Cusco's trademark blue steel end brackets, the strut brace installs easily at the front upper strut mounts using existing hardware. While direct-bolt fitment is standard, certain trims (Sport and Grand Touring) may require Mazda Genuine Air Cowl Part # N244-56-35X to complete the install. Designed with motorsport-derived engineering and precision fitment, this Cusco brace is a popular upgrade for MX-5 owners seeking enhanced handling without sacrificing daily drivability.
