Perrin Performance Pitch Stop Mount for 2004–2021 Subaru WRX STI

Description

Reduce drivetrain shudder under hard acceleration by installing a Perrin Performance Pitch Stop Mount. Subaru’s with power and drivetrain upgrades will need Perrin Performance’s more aggressive option.

Under hard acceleration, the drivetrain is twisted front to back from front axle torque twist. To control this front to back twisting, Subaru created a pitch stop mount. The factory pitch stop is made of plastic with soft rubber bushings, allowing for a significant amount of movement under hard driving conditions, creating drivetrain slop and shudder. The Perrin Performance Pitch Stop Mount controls the movement of the drivetrain in both on- and off-throttle driving giving the driver a more positive feel and literally putting more power to the wheels by eliminating lost energy.
