1990–1997 Mazda Miata NA

Part #: 404 477 A

Overview

The Cusco Lower Arm Bar Ver. 2 for the Mazda Miata NA is a high-performance suspension upgrade designed to enhance the vehicle's chassis rigidity and handling capabilities. Engineered specifically for enthusiasts who seek improved response and stability during spirited driving or track days, this front lower arm bar offers a significant upgrade over the stock suspension components.

By reinforcing the suspension mounting points, this lower arm bar helps reduce body flex and suspension alignment changes that can occur during aggressive cornering. As a result, you'll experience more precise steering, better traction, and improved overall vehicle control, making it an ideal choice for both street and track use.
