Perrin 93-21 Subaru Impreza / 04-21 STI / 02-21 WRX Pitch Stop Mount - Blue - PSP-DRV-101BL

Control Drivetrain Movement. Under hard acceleration, the OEM pitch stop allows the drivetrain to twist front to back from front axle torque twist, creating drivetrain slop and shudder. The PERRIN Pitch Stop Mount controls drivetrain movement in both on and off throttle driving, delivering a more positive feel and putting more power to the wheels by eliminating lost energy.

Race Series Design. The PERRIN Race Series Pitch Stop is designed for track use, pairing a 95a front bushing with a 73a rear bushing to keep the drivetrain locked down under hard acceleration, braking, and cornering. Because it's stiffer than stock, expect some added NVH (noise, vibration, harshness).

Street Series Design. The PERRIN Street Series Pitch Stop is designed for daily driving, pairing a 95a front bushing with a 62a rear bushing that delivers a feel slightly stiffer than the Subaru Group N mount. This keeps the drivetrain under control with a noticeable increase in stiffness, while keeping NVH and drivetrain harshness low for everyday driving.

Built To Outlast Rubber. The PERRIN Pitch Stops use polyurethane bushings that resist wear and are built to outlast the life of your car, unlike the OEM rubber bushings that break down over time and eventually cause the mount to fail.

Construction. The PERRIN Pitch Stop Mounts are constructed from CNC-machined 6061-T6 aluminum and anodized for long-term durability and corrosion resistance.
