Description

The CUSCO Type MZ Limited Slip Differential (Rear) is a high-strength, high-preload mechanical LSD engineered for the late-model GR Yaris (GXPA16, April 2024 onwards) where maximum and immediate locking force is prioritized. Characterized by its robust “D Size” clutch pack and high 8-10 kgf·m initial torque range, the Type MZ is designed for aggressive traction demands, high-torque applications, and competitive environments requiring instantaneous differential response without progressive engagement.

Product Highlights

🏁 High-Preload “MZ” Design for Immediate Lock
Engineered with a high initial torque range of 8-10 kgf·m, the Type MZ delivers near-instantaneous clutch pack engagement. This design prioritizes maximum and immediate locking force over progressive feel, ideal for high-torque, high-grip, or applications where differential sensitivity is secondary to outright traction.

🔧 Comprehensive Cam Angle & Operation Lineup
Offers the same full spectrum of lock-up characteristics as the RS series, allowing precise tuning of vehicle dynamics for different disciplines:

• 1-Way (4.5°): Lock on acceleration only. For pure, aggressive traction focus on corner exit.

• 1.5-Way (55°/20°): Strong lock on acceleration, moderate lock on deceleration. Balances exit traction with entry stability.

• 1.5-Way (55°/20°) – Alternate Group: Part of the 1.5&2-Way cam series, offering a specific ramp angle profile.

• 2-Way (55°/55°): Equal, aggressive lock on both acceleration and deceleration. Maximizes rear-end stability and rotation control, ideal for drift or specific circuit tuning.

⚡ High-Torque & Durability Focus
The high initial preload and “D Size” clutch pack are built to handle significant power and stress, making it suitable for modified vehicles, high-grip tire compounds, and disciplines where differential slip must be minimized.

🎯 Late-Model GR Yaris Specific
Designed and validated for the GR Yaris (GXPA16) from April 2024 onwards, compatible with both the GR-DAT (8AT, 4WD) and 6MT (4WD) drivetrains.

Selection & Professional Notes

🔍 Choosing Type MZ vs. Type RS:

• Choose Type MZ (8-10 kgf·m) if your priority is maximum, immediate locking force with less focus on progressive modulation. Ideal for high-power cars, drag-influenced circuits, or drivers who prefer a very direct, “locked” feel.

• Choose Type RS (2-4 kgf·m) if you require smooth, progressive engagement and fine driver modulation, which is critical for high-downforce cars, slick tires, and experienced drivers managing rotation at the limit.

⚠️ Mandatory Professional Installation & Setup
This is a precision racing component. Installation requires complete differential disassembly, expert shimming, and specific knowledge. Must be installed by a certified differential/racing specialist. Proper break-in with CUSCO LSD-specific fluid is critical.

⚙️ Intended for Aggressive Competition Use
The Type MZ’s high preload is optimized for competition vehicles where instantaneous traction is the primary goal. Its engagement characteristic is more abrupt than the Type RS.
