Description

The CUSCO TypeOS Rear Strut Bar (Oval Shaft Type 1) is a performance-focused chassis reinforcement component engineered to increase rear structural rigidity and enhance handling balance for the GR Yaris. Utilizing CUSCO’s proven TypeOS (Type Optimal Structure) design with an oval shaft construction, this strut bar effectively reduces chassis flex, improving stability, traction, and overall vehicle composure during spirited and track driving. Installation requires interior modification for a secure, integrated fit.

Product Highlights

🏗️ TypeOS Oval Shaft Design for Optimized Rigidity
Features CUSCO’s TypeOS engineering with an oval cross-section shaft that provides superior torsional stiffness and efficient load distribution, effectively tying the rear suspension points together to minimize chassis flex.

🔄 Enhanced Rear Stability & Traction
By solidifying the rear chassis structure, this bar reduces body roll and improves weight transfer management, leading to increased rear-end stability, better traction on corner exit, and a more predictable handling balance.

⚖️ Improved Overall Chassis Balance
Working in conjunction with a front strut bar, this rear bar helps achieve a more neutral and responsive chassis character, sharpening turn-in response and increasing driver confidence during aggressive maneuvers.

🔧 Interior Modification Required for Installation
To ensure optimal mounting and performance, interior cutting/modification is required to accommodate the bar’s mounting points. This allows for a secure, integrated installation that maximizes effectiveness.

⏱️ Straightforward Mechanical Installation
Once interior modifications are complete, the mechanical installation is efficient with an estimated installation time of 1.0 hour, making it a manageable upgrade for experienced installers.
