Cusco LSD MZ 1.5 way ND5RC MIATA

Cusco is well-known for making performance parts for Japanese sports cars, especially for handling and drivetrain upgrades. This 1.5-way Limited Slip Differential (LSD) is a prime example, designed specifically for the ND5RC Miata. If you're looking to improve your Miata's traction and cornering ability, especially during spirited driving or track use, this differential can make a significant difference.

This MZ type LSD from Cusco uses a clutch-based system. The 1.5-way design means it engages more aggressively on acceleration than deceleration. This helps put power down effectively when you're getting on the throttle coming out of a corner, while still allowing for some differential action during braking or engine braking. It’s a popular setup for drivers who want a predictable and strong lock-up during acceleration, which can help rotate the car and maintain stability. The internal components are well-built to handle the stresses of performance driving, ensuring consistent performance over time.

When installing a new differential like this, it's important to follow the manufacturer's break-in procedure. This typically involves a period of gentle driving with specific mileage and speed limitations, followed by a fluid change. This process helps seat the clutch plates properly and ensures the longevity of the LSD. You'll also need to use the correct differential fluid, which is usually a specialized gear oil with friction modifiers. Make sure to consult the installation manual for the exact break-in and fluid recommendations.
