JDM STI Flexible Trunk Bar Subaru 2022-2026 WRX

This new flexible part for mounting inside the trunk was developed based on knowledge gained from the Nürburgring 24-Hour Race. It features the same pillow ball mechanism as conventional tower bars, which effectively transmits lateral forces while absorbing vertical forces from road imperfections, and a draw mechanism that applies preload to reduce slight hysteresis, such as play or rattle, in the vehicle body, resulting in improved steering response and stability while also providing a comfortable ride. The STi Flexible Trunk Bar (ST20503V2010) is a high-performance chassis brace designed for the Subaru WRX S4 (VB) that connects two aluminum pieces with central pillow ball joints. It enhances cornering, straight-line stability, and ride comfort by managing lateral forces while absorbing vertical road surface vibrations.

Features:
- Design: Features a split-aluminum structure connected by central pillow ball joints for improved flexibility.
- Performance: Significantly improves handling, steering response, and stability.
- Comfort: Maintains ride comfort by absorbing vertical forces (road gaps) rather than transferring them to the chassis.
- Technology: Utilizes a "draw mechanism" that applies preload to reduce hysteresis, minimizing rattles and play.
- Compatibility: Specifically designed for the Subaru WRX S4 VB (2021/11+).
- Origin: Developed based on technology from the Nürburgring 24-Hour race.
- Genuine Subaru Part STI Performance

What To Expect:
- Responsiveness of the car improves, which delivers spontaneous proper steering.
- As steering requires less attention from a driver, they can be more attentive to the surrounding environment such as pedestrians crossing the road and cars running side by side, and thus feel at ease and relaxed to drive.
- The Flexible Tower Bar exerts its effect even at low speeds such as when a car is in reverse. It allows a driver to eliminate unnecessary steering maneuvers because they can control the car exactly as they intend to do.
- Furthermore, it stabilizes the car when running, so passengers do not have to strain their body muscles and feet to support themselves against jolting, and the risk of carsickness is reduced. Therefore not only the driver but also all passengers in the car can be more comfortable and enjoy the ride.
