SuperPro Motorsport Rear Differential Mount Bushing Kit for 2004-2015 Mazda MX-5 Miata & RX-8 (SPF3404-80K)

Fits 2004-2011 Mazda RX-8 and 2006-2015 Mazda MX-5 Miata (all models including Club, Touring, Grand Touring, and R3).

The SuperPro SPF3404-80K Motorsport Rear Differential Center Support Bushing Kit is designed to drastically reduce the deflection of the factory rubber mount under changing loads. By securing the differential housing, this kit improves throttle response and allows for more precise control over the car's cornering attitude, as the drivetrain reacts more directly to throttle inputs.

This "Motorsport" version features a higher durometer material for maximum performance and drivetrain stability. While it provides sharper feedback than the standard 70K street version, it may introduce a slight increase in NVH (noise, vibration, and harshness). This is an essential upgrade for track-driven vehicles or enthusiasts looking to eliminate the "sloppy" feeling of the OE mount.
