What is the difference between a 1.5-way and a 2-way LSD?

A 2-way LSD, like this Cusco Type RS, locks up during both acceleration and deceleration. A 1.5-way LSD locks up during acceleration and partially during deceleration. The 2-way action provides more stability during braking and cornering.

What else might I need to install this LSD?

Installation typically requires specialized tools for differential work. You will also need appropriate differential fluid, which is not included with the LSD unit. It's recommended to consult the manufacturer's installation instructions or a service manual for a complete list of requirements.

How does this LSD affect daily driving?

The Cusco Type RS is designed for smooth engagement during normal driving, so it shouldn't be overly intrusive. However, you might notice a slight difference in how the rear end behaves during low-speed turns. The primary benefit is realized during spirited driving and cornering.

About this part

Product Details

This Cusco Type RS 2-Way Limited Slip Differential (LSD) is designed specifically for your 1994-1997 and 1999-2005 Mazda Miata. What you get in this package is the LSD unit itself, ready to be installed into your Miata's rear differential housing. This isn't just about putting power down; it's about controlling it, especially when you're pushing your car hard.

The Type RS is a well-built unit that offers a unique clutch system. It's designed to provide a smooth engagement when you're just cruising, but it locks up more aggressively under acceleration. This means you get improved traction when you need it most, whether you're exiting a corner or accelerating on a straight. The 2-way action means it locks up during both acceleration and deceleration, which helps stabilize the rear end during braking and cornering. This can lead to more predictable handling and a more connected feel to the road. The LSD 177 L2 is built with precision and durability in mind, aiming to handle the demands of spirited driving.

Installing an LSD is a significant upgrade for your Miata's drivetrain. It changes how the rear wheels receive power, especially when one wheel starts to lose traction. This unit is a popular choice for Miata owners looking to enhance their car's performance on track days, autocross events, or even just for a more engaging street driving experience. Remember that installing an LSD typically involves removing and reinstalling the differential, so it's a job that requires specific tools and knowledge. It's often recommended to have this professionally installed or to consult detailed service manuals for the correct procedures and any additional parts you might need, such as differential fluid.
