Description

The CUSCO S-MCB Strut Bar Rear is a cutting-edge rear chassis reinforcement component designed to elevate the structural integrity and handling balance of the GR Yaris. Utilizing advanced S-MCB (Sheet Molding Carbon & Basalt) composite technology, this strut bar provides exceptional torsional rigidity to the rear chassis, enhancing stability, turn-in response, and overall vehicle composure. Compatible with both early and late-model GR Yaris variants.

Product Highlights

🏗️ Advanced S-MCB Composite Construction
Crafted from high-performance S-MCB (Sheet Molding Carbon & Basalt), a hybrid composite that delivers an outstanding strength-to-weight ratio. This material provides superior rigidity and effective vibration damping compared to conventional steel or aluminum bars, without adding significant weight.

🔄 Enhanced Rear Chassis Rigidity & Stability
By solidly connecting the rear suspension mounting points, this strut bar significantly reduces chassis flex under cornering and load transfer. This results in a more stable and predictable rear end, improved traction on exit, and a more balanced overall handling character.

⚡ Improved Turn-in Response & Cornering Balance
A stiffer rear chassis improves the vehicle’s rotational response, leading to sharper initial turn-in and a more neutral balance through corners, reducing understeer and increasing driver confidence.

🔧 Universal Fit for Early & Late Models
Engineered for compatibility with both early and late-model GR Yaris (GXPA16), making it a versatile upgrade for all generations of the platform.

⚠️ Interior Modification Required for Installation
Installation involves modification to the interior trim panels to accommodate the bar’s mounting points. This ensures a secure, integrated fit but requires careful workmanship.

Installation & Performance Notes

🔧 Professional Installation Highly Recommended
Due to the required interior modification and the need for precise alignment and secure mounting, installation should be performed by an experienced technician familiar with interior trim work and performance chassis components.

🏁 Ideal for Track & Performance-Oriented Builds
A critical upgrade for drivers who prioritize chassis balance and stability at the limit. Especially beneficial when paired with a front S-MCB strut bar for a complete, high-rigidity chassis setup.

🎯 Noticeable Improvement in High-Speed Stability
Drivers can expect a tangible increase in rear-end stability during high-speed cornering, aggressive direction changes, and under hard braking, contributing to a more planted and confidence-inspiring drive.
