The Cusco LSD Type RS 1.5 Way is a high-performance limited slip differential designed for the Mazda Miata ND (2016 and newer). Engineered to enhance traction and handling, this LSD features a spring mechanism that absorbs initial torque, providing a smoother engagement compared to the Type MZ. Its low initial torque design reduces power loss, resulting in more efficient power transfer to the wheels. The Type RS allows for two of three adjustable settings through a simple overhaul, giving drivers flexibility to customize their driving experience. Constructed with precision components, it offers improved response and reduced friction, which can lead to lower lap times and better overall performance on both street and track.

This differential is specifically compatible with Mazda Miata ND models from 2016 onward, fitting vehicles equipped with the LSD 431 L15 unit. It is intended for enthusiasts seeking improved traction, especially during spirited driving or racing scenarios. The installation is a direct replacement for the stock differential, providing a bolt-on upgrade that enhances cornering and acceleration. The kit includes the LSD unit and necessary components for installation. Suitable for track days, autocross, or daily driving, this Cusco LSD Type RS delivers reliable, high-quality performance with adjustable settings for tailored handling characteristics.

Overview

A Cusco Limited Slip Differential offers the absolute best in traction. Cusco LSD allow you to choose 2 of 3 settings with each unit just with a simple overhaul. The Type RS springs absorb the initial torque. Compared to the Type MZ, the Type RS s initial torque comes on more gently. The response of the RS has lower friction and in turn, is transfers power to the ground more efficiently. The Low Initial Torque means Less Power Loss. This equates to lower lap times, even for a mildly tuned vehicle. The low pressure on the clutch plates improves durability and lowers chatter. To top it off, the reduced pressure allows the driver to change the LSD oil less frequently. Steady coil movement is assured by special precision springs set in the pressure plate. These springs are made to be resilient and allow for stable operation. Because these plates do not utilize a cone clutch, they do not stick and allow for increased longevity. The Type RS transfers extreme power without slipping and responds quickly with pedal inputs. This differential is ideal for drag racing or going for drifting. Contact Us with any questions..

Cusco recommends the following setups for the following drivetrains.

  • 1 way LSD: Specially suited for front wheel drive cars and AWD front axle cars.Activates under acceleration, and acts as a true LSD when the throttle is off.
  • 1.5 way LSD: Activates under acceleration with less under-steer under deceleration than on a 2 way LSD. Recommended for those who want to reduce under-steer.
  • 2 way LSD: Recommended on rear wheel drive cars and AWD rear axle cars. Activates on both acceleration and deceleration. Recommended for those who prefer aggressive driving and big angle drifting.
