Perrin Neon Yellow Rear Strut Tower Bar 2015-2021 WRX / 2015-2021 STI | Carbon Fiber Construction | Chassis Brace
Overview
The Perrin Neon Yellow Rear Strut Tower Bar is designed specifically for the 2015-2021 Subaru WRX and WRX STI models to enhance chassis rigidity and improve steering precision. By connecting the rear shock towers, this brace effectively reduces flex during cornering, resulting in a more responsive and stable driving experience. It’s an ideal upgrade for enthusiasts looking to sharpen handling without compromising daily drivability.
Engineered with a focus on strength and lightweight performance, the brace features a 100% carbon fiber hollow bar combined with CNC machined aluminum feet finished in black anodizing. This combination provides superior stiffness compared to traditional aluminum tubing while adding a striking visual accent to the rear strut tower area. Perrin’s attention to detail and quality manufacturing ensure a durable and precise fitment tailored to the VA chassis.
In real-world driving, this rear strut tower bar transfers loads between the shock towers during compression and tension, reducing understeer and enhancing cornering stability. It also helps minimize tire wear and metal fatigue in the shock tower mounts, contributing to the longevity of your Subaru’s chassis. This upgrade is a practical and effective way to elevate your WRX or STI’s handling dynamics while maintaining OEM-level fit and finish.
