Show original supplier description
The Hardrace Rear Upper Rear Arms, part number HR-8544, are a 2-piece set specifically designed for the Miata ND. These adjustable arms are constructed from a unique high-density steel, intended to enhance vehicle stability during high-speed maneuvers and aggressive cornering. They come equipped with premium bushings to ensure optimal performance and longevity. This product is an adjustable arm, which is a key feature for fine-tuning suspension geometry. The high-density steel construction contributes to the overall robustness of the component, ensuring it can withstand the demands of spirited driving. The pillow ball design, indicated in the product name, suggests the use of spherical bearings which allow for more precise movement and reduced deflection compared to traditional rubber bushings.
