Description

Engineer sharper turn-in and more precise front-end feedback into your WRX S4 with an STI-engineered flexible tower bar (strut brace). This isn’t a simple rigid bar; it’s an intelligent component designed to strategically increase chassis rigidity where it benefits handling while maintaining compliance for ride quality.

Product Highlights

• Intelligent Flexible Joint Design: The key feature is a unique ball-joint-like connection at the center of the bar. This allows it to flexibly absorb vertical shocks and vibrations from the road (like bumps and potholes) while significantly increasing lateral rigidity against the forces generated during hard cornering.

• Enhanced Cornering Precision & Feedback: By resisting lateral flex across the front strut towers, the bar sharpens steering response, improves turn-in precision, and provides more direct communication from the front tires. It makes the front of the car feel more “tied together” during aggressive driving.

• Balanced Performance Upgrade: This design philosophy offers a performance benefit over a completely rigid bar by reducing the transfer of harsh vertical vibrations into the chassis, aiming to preserve more daily driving comfort while still delivering handling gains.
