Description

The CUSCO Lightweight Rear Differential Mount Bracket is a high-performance, weight-saving component engineered to replace the factory rear differential mount bracket in the late-model GR Yaris. Precision-machined from billet aluminum and finished in a durable gunmetal anodized coating, this bracket provides a significant 0.66 kg (66%) weight reduction over the OEM part while maintaining or exceeding OEM strength. This strategic weight saving contributes to reduced unsprung mass, improving suspension response and overall vehicle dynamics.

Product Highlights

⚖️ Significant Weight Reduction
Weighing only 0.63 kg, this bracket is a remarkable 0.66 kg (over 50%) lighter than the stock component, contributing directly to reduced overall vehicle weight and unsprung mass for sharper handling and acceleration.

🏗️ Billet Aluminum Construction & Durability
CNC-machined from a solid block of high-grade billet aluminum, ensuring exceptional strength, rigidity, and precise fitment. The gunmetal anodized finish provides superior corrosion resistance and a premium, technical appearance.

🎯 Enhanced Suspension & Drivetrain Response
By reducing unsprung weight at a critical drivetrain mounting point, this upgrade helps improve suspension reaction time and drivetrain responsiveness, allowing the rear differential and suspension to react more quickly to road inputs and driver commands.

🔧 Direct Bolt-On Replacement
Engineered as an exact, direct replacement for the factory rear differential mount bracket. Installation requires no modification and has an estimated time of 1.0 hour, making it a straightforward upgrade for both enthusiasts and professional installers.

🇯🇵 Late-Model GR Yaris Specific
Designed exclusively for the late-model GR Yaris (GXPA16, April 2024 onwards), compatible with both GR-DAT (8AT, 4WD) and 6MT (4WD) models.

Installation & Performance Notes

✅ Professional Installation Recommended
While a direct bolt-on, installation involves supporting the differential and proper torque sequencing. Professional installation ensures safety and correct alignment.

🔩 Part of a Comprehensive Weight Reduction Strategy
Pairs effectively with other CUSCO lightweight components such as strut bars, chassis braces, and suspension arms to achieve a more significant cumulative reduction in unsprung and overall vehicle weight.

🏁 Benefits for Performance Driving
The weight savings, though focused on a single component, contribute to a more agile and responsive chassis feel, particularly beneficial during rapid direction changes, cornering, and acceleration on track or spirited drives.
