Perrin Street Series Pitch Stop Mount Red 2002-2026 WRX / 2004-2021 STI / 2005-2009 Legacy GT / 2020-2024 Legacy XT / 1993-2024 Impreza / 2019-2024 Ascent / 2013-2024 Crosstrek | Polyurethane Bushings | Drivetrain Mount
Overview
The Perrin Street Series Pitch Stop Mount is engineered to reduce drivetrain shudder and control movement under hard acceleration for a wide range of Subaru models including WRX, WRX STI, Legacy, Impreza, Ascent, and Crosstrek. Designed specifically for daily driving, this mount offers a noticeable increase in drivetrain stiffness without compromising comfort or introducing excessive noise and vibration. It is ideal for Subaru enthusiasts seeking improved throttle response and a more connected driving experience without sacrificing street-friendly refinement.
Built with precision CNC-machined 6061-T6 aluminum and finished with a durable anodized coating, the Street Series Pitch Stop Mount features high-quality polyurethane bushings that outperform OEM rubber components in longevity and performance. Perrin’s engineering approach balances stiffness and compliance by pairing a 95a durometer front bushing with a softer 62a rear bushing, delivering enhanced control over drivetrain torque twist while maintaining low NVH levels for everyday usability.
By minimizing drivetrain slop and energy loss caused by the stock mount’s rubber bushings, this pitch stop mount improves power delivery to the wheels and sharpens throttle response. Subaru owners will appreciate the improved engagement and reduced shudder during acceleration, making this an effective upgrade for both spirited street driving and moderate performance use. The Street Series is a practical choice for those who want durable, high-quality drivetrain control without the harshness of race-oriented mounts.
