The KIT6000AK is SuperPro's suspension bushing kit for the NC MX-5 Miata. Including a comprehensive range of bushing upgrades throughout the suspension to overhaul and improve the performance and responsiveness of your Miata or to form an ideal baseline for other suspension and handling upgrades. This kit includes select alignment-adjustable bushings. The kit will upgrade the design and materials over the OEM bushings for superior handling, greater responsiveness, and a massively extended service life - as well as optimizing front-end alignment around additional positive caster and the ability to fine tune and bring in additional negative camber.
