Mazda MX5 NB/NC/RX8 Fuji Super LSD Upgrade Kit

The Mazda RX8 and Mazda MX5 NB/NC, equipped with the Fuji Super LSD, are known for their performance, but their OEM Limited Slip Differentials (LSD) come with a significant flaw—the friction cones behind the spider gears tend to break, even on low-mileage cars. This leads to reduced traction and performance, frustrating many RX8 and MX5 NC owners alike.

RacingDiffs offers the ultimate solution with our Mazda RX8 & MX5 NC LSD upgrade kit. We replace the fragile friction cones with high-performance clutches and preload shims to significantly improve stopping force. Our kit also includes 4x stronger springs to replace the factory components, ensuring long-lasting durability and enhanced performance.

Whether you own an RX8 or an MX5 NC, this upgrade doesn't just fix the problem—it improves your LSD’s performance by up to 4 times compared to the stock version. Say goodbye to one-wheel-spin and enjoy improved traction, smoother handling, and superior control on both the street and the track.
