Best bang for the buck chassis stiffener mod for your MX-5 Miata! These units replace the stock rubber door bushings on your Miata with solid delrin door bushings. They allow your door to more rigidly connect with the chassis, resulting in a noticeable reduction in chassis flex in corners and going over bumps. Less chassis flex results in your suspension doing the work it was meant to do.

Includes 2 Delrin door bushings, and brand new stainless steel fasteners.
Fits NA, NB, NC, and ND MX-5 Miatas, 1990-2022.
