Overview
The Perrin Street Series Pitch Stop Mount is engineered to reduce drivetrain shudder and control engine movement under hard acceleration for a wide range of Subaru models including WRX, STI, Legacy, Impreza, Ascent, and Crosstrek. Designed specifically for daily driving, this mount offers a noticeable increase in stiffness over the OEM rubber mount while maintaining comfort and minimizing noise, vibration, and harshness (NVH). It’s ideal for Subaru enthusiasts seeking improved drivetrain feel without sacrificing everyday drivability.
Built with precision CNC-machined 6061-T6 aluminum and finished with a durable anodized coating, the mount features high-quality polyurethane bushings that outlast traditional rubber components. Perrin’s engineering approach balances performance and longevity, using a 95a durometer front bushing paired with a softer 62a rear bushing to provide controlled drivetrain movement while absorbing unwanted vibrations. This design philosophy ensures a reliable upgrade that enhances the driving experience without introducing excessive harshness.
For Subaru owners, controlling drivetrain pitch is crucial to maximizing power delivery and reducing energy loss caused by engine movement. The Street Series Pitch Stop Mount improves throttle response and overall drivetrain engagement, making acceleration smoother and more direct. This mount is a practical upgrade for daily drivers who want enhanced control and durability while preserving comfort on the street.
