Overview

These sway bars help keep the body under control, allowing for flatter cornering and quicker reactions. They are hot formed from 4140 CrMo spring steel for increased strength.

The set includes adjustable front and rear sway bars, each with three settings for fine-tuning handling balance. The front bar is a 1.125" tubular design with a 0.188" wall thickness, while the rear bar is a solid 0.625". The set comes complete with polyurethane bushings, brackets, grease, and front bar stoppers.

Show original supplier description

Manufactured from robust 4140 CrMo spring steel, these hot-formed bars offer superior strength and durability compared to cold-formed options. The design aims to maintain a neutral handling balance while providing adjustability for personalized driving dynamics. The front bar offers two settings, and the rear bar offers three, allowing precise tuning of your Miata's response to your driving style. These sway bars are specifically designed for the NB chassis, measuring 1.0 inch solid in the front and 0.625 inch solid in the rear. They are a direct upgrade from stock sways, offering a noticeable improvement in stability and grip, particularly on their softer settings which are already stiffer than factory Mazdaspeed units. The kit includes durable urethane bushings with waterproof grease and all necessary mounting brackets. Installation is described as straightforward, with some users recommending watching the provided installation video for ease. However, some reviews mention that end link removal can be challenging due to rust or the nature of the stud-bolt design on certain Miata models, potentially requiring additional tools or techniques. It is also advised to consider replacing end links concurrently if they are rusted or damaged, as this can simplify the installation process and ensure optimal performance. The product is backed by a lifetime warranty.
