Racing Beat-designed Adjustable HD (Heavy Duty) Sway Bar Links are a direct swap with the 90-97 and 99-00 (rear only) Miata factory links and provide the performance enthusiast the ability to set either front or rear sway bars to a "neutral position" while the chassis is at ride height to avoid pre-loading of the bar. The experienced enthusiast may wish to purposely "pre-load" the bar to create a specific handling characteristic to induce either a mild understeer or over steer condition. The CNC-machined aluminum end housings are fitted with urethane bushings to further reduce flexing - as compared to stock rubber bushing links. Each set contains two (2) links to serve one (1) sway bar.These links have been designed for use on the stock bar and all Racing Beat anti-roll bars.
