Product Description

The Whiteline W93582 is a rear differential bushing kit for the full ND-generation Mazda MX-5 Miata lineup, covering Club, Grand Touring, Sport, and RF hardtop trims across the 2016-2025 model range, including the special-edition 100th and 35th Anniversary models. It replaces the factory differential mount bushings, which are a common weak point for drivetrain feel on a car this focused on direct, responsive handling.

Maintaining correct pinion angle matters more than it might seem - a differential that's allowed to shift under load changes the angle at which power is delivered to the rear wheels, which shows up as inconsistent shift feel and torque delivery, especially noticeable during hard acceleration or track driving. By keeping that mount rigid and consistently located, this kit improves gear shift precision and reduces the initial torque loss that comes from a differential flexing in its mounts before power actually reaches the wheels.

Given the Miata's reputation as a precision-focused sports car, a driveline bushing upgrade like this is a natural fit for anyone doing track days or simply wanting sharper, more direct power delivery from a stock or lightly modified ND. This kit is sold as a complete differential bushing set rather than an individual bushing, covering the full mounting point in one purchase.
