Perrin Pitch Stop Brace 2015-2021 WRX / 2015-2021 STI | Reinforced Drivetrain Support | Chassis Bracing & Clutch Line Upgrade
Overview
The Perrin Pitch Stop Brace is a critical reinforcement solution designed specifically for the 2015-2021 Subaru WRX and WRX STI models. These vehicles experience constant drivetrain movement during normal driving, which places stress on the OEM pitch stop brackets. Over time, this stress can lead to bracket failures, including tearing and weld breakage at the firewall. The Perrin Pitch Stop Brace addresses this issue by strengthening the connection points, significantly reducing the risk of damage and failure.
Engineered with precision and durability in mind, the Perrin Pitch Stop Brace kit includes robust left and right braces that work in tandem to stiffen the OEM mounting brackets. This design philosophy focuses on preventing flex and movement that can compromise the drivetrain’s stability. Additionally, the kit features a stainless steel braided Teflon clutch line, which not only enhances the engine bay’s appearance but also improves clutch pedal feel and response. This dual approach of chassis bracing and hydraulic line upgrade sets Perrin apart as a thoughtful solution for Subaru enthusiasts.
For Subaru WRX and STI owners, this brace offers tangible benefits beyond just preventing bracket failure. By reducing firewall flex during clutch engagement, especially on cars equipped with stiffer aftermarket clutches, the brace improves pedal consistency and driver confidence. This upgrade is a practical investment in drivetrain reliability and overall vehicle refinement, making it a valuable addition for daily drivers and performance enthusiasts alike.
