Description

The CUSCO Adjustable Rear Lower Arm (Front Side) is a high-performance suspension linkage component engineered to provide critical rear-wheel alignment adjustability for the GR Yaris. As a direct replacement for the factory arm, it enables precise tuning of rear suspension geometry, essential for optimizing handling balance, tire contact, and stability—especially in lowered or competitively tuned setups.

Product Highlights

🎯 Enhanced Rear Suspension Tuning
Provides precise adjustment of key rear alignment parameters, allowing for optimal camber and toe settings to match your tire, suspension, and driving requirements.

🔧 Direct Bolt-On Design
Engineered as an exact, high-strength replacement for the OEM rear lower arm (front side), ensuring straightforward installation without vehicle modification.

📏 Extended Adjustment Range
Offers an adjustment range of Factory ±10mm, giving significant flexibility to correct alignment after lowering or to fine-tune handling for track, autocross, or performance street use.

📄 Validated Strength & Durability
Includes a strength evaluation sheet, certifying the arm’s construction and load-bearing capability under high-stress driving conditions for assured safety and reliability.

⚙️ Crucial for Geometry Correction After Lowering
An essential upgrade for any lowered GR Yaris, as it restores proper suspension operating angles, preventing compromised handling, uneven tire wear, and loss of rear-end stability.
