Description

The CUSCO Type RS Limited Slip Differential (Rear) is a high-capacity, competition-oriented mechanical LSD engineered exclusively for the late-model GR Yaris (GXPA16, April 2024 onwards). Featuring a larger “D Size” clutch pack with 12 high-rate RS springs as standard, it is built for extreme durability and aggressive locking performance. Designed for both GR-DAT (8AT) and 6MT 4WD models, it offers a comprehensive lineup of cam angles and operating methods to precisely tailor rear differential behavior for maximum traction, stability, and driver control in competitive environments.

Product Highlights

🏁 High-Capacity “D Size” RS Design
Engineered with a larger diameter (“D Size”) clutch pack and 12 high-rate RS springs as standard, providing immense clamping force, superior heat dissipation, and exceptional durability for the most demanding track and competition use.

🔧 Comprehensive Cam Angle & Operation Lineup
Offers a full spectrum of lock-up characteristics to fine-tune vehicle dynamics:

• 1-Way (4.5°): Lock on acceleration only. Pure traction focus for 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.

⚡ Competition-Optimized Initial Torque
Features a sensitive and consistent 2-4 kgf·m initial torque range, allowing for smooth, progressive engagement that gives advanced drivers precise modulation over the locking force.

🎯 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 the Correct Cam Profile:

• For Maximum Traction (Circuit/Time Attack): 1-Way (4.5°) or 1.5-Way (55°/20°) from the C-series.

• For Balanced Performance & Adjustability: 1.5-Way (55°/20°) from either series.

• For Maximum Rotation Control (Drift/Pro Racing): 2-Way (55°/55°).

⚠️ 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 Dedicated Performance Use
The Type RS’s aggressive design and sensitive tuning are optimized for competition vehicles running on high-grip tires. It is not intended for casual street use.
