Perrin 15-17 Subaru Impreza WRX / STi Pitch Stop Mount - Black

Upgrading your pitch stop mount is one of the most effective ways to reduce drivetrain slop and improve throttle response in turbo Subarus. The Perrin Pitch Stop Mount replaces the weak, flexible OEM piece with a precision-engineered billet aluminum mount that delivers dramatically sharper engine feedback and reduced movement under hard acceleration, deceleration, and shifting.

This component connects the top of your engine to the firewall, acting as a brace to limit engine pitch and movement. The factory mount is made of soft rubber, which flexes easily under load—leading to drivetrain lash, vague shifting, and added stress on other mounts. Perrin's mount eliminates these issues with a rigid aluminum frame and polyurethane bushings tuned to absorb harsh vibrations while significantly reducing unwanted motion.

The result is a more solid, responsive feel every time you get on the gas or shift gears. Throttle inputs feel immediate, shifts become crisper, and the car just feels more connected as a whole. Enthusiasts often pair this upgrade with stiffer motor mounts or transmission mounts for an even more dialed-in driving experience.
