Which cars does the Type MZ 2-Way Rear LSD for ZN8 fit?

Cusco USA lists part number LSD 6C1 J2 for the Toyota GR86 (ZN8, 2022-2026) and the Subaru BRZ (ZD8, 2022-2026). The Type MZ 2-Way Rear LSD for ZN8 replaces the factory rear differential, so check the notes on this page for any model or transmission limits before ordering.

What does 2-way mean?

A 2-way LSD locks under deceleration as well as acceleration. The driven wheels stay tied together when the driver lifts or brakes, which keeps the car stable and predictable in a slide and on hard braking. The trade-off is more push on corner entry and heavier manners at parking speeds, so it suits drift and dedicated competition cars.

How does the Type MZ differ from the Type RS?

The Type MZ uses a high-pressure cone spring that works against the activation pressure, which gives it the highest initial torque of any Cusco LSD and a linear build to full lock. The Type RS uses coil springs for a lower initial torque and smoother, quicker engagement, which makes it the friendlier choice for a street car.

What initial torque does it use?

Cusco quotes 7 to 9 kgf-m of initial torque for this unit, which is the locking force the differential applies before the engine sends any power through it. Lower values feel smoother on the road; higher values hold the inside wheel harder on corner exit.

What should I know before installing it?

The differential carrier must be removed from the car to fit the Cusco unit, so most owners have a drivetrain specialist do it. Plan on fresh gear oil, since Cusco sells its own LSD oil for clutch-type differentials, and read the notes on this page for any extra parts Cusco says the job needs.

Cusco Type MZ 2-Way Rear LSD for ZN8 Toyota GR86 and ZD8 Subaru BRZ

Cusco’s Type MZ 2-Way Rear LSD for ZN8 Toyota GR86 and ZD8 Subaru BRZ replaces the factory rear differential with a clutch-type limited-slip unit built around a high-pressure cone spring, which gives the Type MZ the highest initial torque of any Cusco LSD. As a 2-way it locks under acceleration and deceleration alike, which keeps the car stable on the brakes and holds both wheels together through a slide. The cone spring brings the clutch pack to full lock at a linear rate, so the locking effect builds predictably. It suits drift, rally and other competition use, where maximum lock in both directions is wanted.

Design and Performance

In the Type MZ the activation pressure works against a high-pressure cone spring, so the diff engages once those opposing forces meet. That cone spring gives the MZ the highest initial torque of any Cusco LSD and brings the clutch pack to full lock at a linear rate, so the Type MZ 2-Way Rear LSD for ZN8 behaves the same way corner after corner.

Features

High-pressure cone spring for the highest initial torque in the Cusco range
2-way action: locks on acceleration and deceleration
Linear build to full clutch-pack lock
Clutch-type multi-plate design in place of the factory rear differential
Built for the GR86 and BRZ

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
